#== v0.13 features. ==

# NOTE— quest states have been rebuilt.

# TAERIN

# Possum

# – An attrition girl — she gnaws, drains… scavenges for items and uses them more effectively.

# – Marsupial Pouch — she’s the only girl who buys combat order slots two at a time!!~

# – Skills: Gnaw, Contagious, Nocturnal, Drain, Scavenge, Curious, and innate Pest Control.

# Kānuka

# – The white tea tree, a shielder who stacks SHIELD for her team, tanking, or spending it all on powerful hits.

# – Skills: Thump, Whomp, Huddle, Windthrow, Fire Eater, Beeloved, and Karaka-mā.

# GOING BUSH — Quest 006 continues

# – The Tangle questline pushes on: from the grove, across the river… and into trouble.

# – New objective types: steps that ask you to bring particular girls along. Pasha and Iris are pretty involved in story beats, so they might be necessary to have in your party sometimes to make story keep going~

# WARDROBE — outfit overhaul

# – The outfit system has been rebuilt, pieces of outfits can be recoloured individually, and there are far more toggles for mixing and matching~

# – New outfits for Hoiho and Papaka. Available to FAVOURED+ supporters.

# – Named NPC portraits in dialogue now track the wardrobe properly~ So your quest bikini pasha, now shows up in dialogue cutscenes too~

# ALSO

# – Hoiho and Papaka both have new hair and skin hues, split onto independent tracks.

# – This might mean that old girls now have new hair and skin colours…

# THE GARDENS

# – The temple gardens are a place that you might have found while adventuring.

# – They were a nice place to take Taerin for a walk… but have now been turned into a place where you can send your most adored girls!!

# – Girls in the Gardens don’t count toward crowding, and gain mood and lose fear each night.

# – It requires [Adoring] love and obedience of 50+, but it’s a good place to store those girls who’re just taking up space… so you can go out and catch all new ones!!

# XXX

# – Scenes can now play out in the environment. The first of these appears in Quest 006 — go foraging and see what happens~

# – Animated love scenes can now play inside ordinary dialogue. So expect more of that in future.

# COMABT

# – Scenery no longer gets caught inside the combat ring.

# — to avoid visual catastrophe in dense foliage, when you enter combat with a lot of plants, they’ll dim so that combat takes priority.

# — objects that have big collision boxes are exempt. Do not stub your toe on logs and big rocks.

# – Persistent statuses and abilities: statuses are now sorted into Superstatus, Modifier and Condition, and cleanses say what they actually clear.

# – Poras and cleanse skills should behave much more predictably.

# – BERSERK added properly. You can’t control your girl, but she’ll hit harder and faster!

# – Skills can now cost HP or SHIELD instead of mana, and that’s indicated properly in their hover-tooltip

# EQUIPS & ITEMS

# – Defeated Taerin can now drop equipment.

# — Drop tables are still small, but go kill some Piwakawaka or Schist, and see what you can find.

# – Item implicits more reliably resolve and display properly in the bag, the shop and on tooltips.

# – New materials, and an antiburn consumable has been added.

# THE TANGLE

# – Is now much bigger — with subzones, new spawn tables, thicker scrub, and a little shortcut to unlock if you have the right team~

# – The world now remembers blocked paths and shortcuts between visits… But please bug report if you have egregious pathing issues or warp into illegal places!

# FIXES

# – Load time might be slightly longer going into denser maps, but performance should be more stable when you get in.

# – Blah blah blah… Various combat and quest sequencing fixes~.

#== v0.12 features. ==

# Going Bush — Quest 006 begins!

# – Act 2 is finally opening up: a new questline pushes us past the coast and deep into the Tangle.

# – Though it’s far from finished, you can start exploring the deeper parts of the wilderness with your party, meet new Taerin, and new challenges.

# TAERIN

# Koru

# – A young silver fern — a little curled-up earth spirit native to the Tangle.

# – She’s a mana-battery, support caster. Her whole deal is feeding the field — her Mana Well quietly drops MP globs for the party to scoop up, so your casters never run dry.

# – Skills: Windstrike, Shed, Mana Gift, Mana Storm, Ngāwhā, Reverie — plus her Mana Well passive.

# – Sprites, portraits, drop table, preferences and features all built.

# Mānukin?

# – Strange bee Taerin have appeared, and they come at you en masse.

# – They seem easy enough to swat away, unless one of their big sisters has decided to come with them…

# – A campfire rest stop has appeared in the Tangle!! Campfires can be used as fast-travel points.

# – If you have the right supplies, your girls can patch themselves up~

# – Sprites, portraits, drop table, preferences and features all built.

# COMABT

# — movement rework!!

# – Everyone in a fight now moves with tactical “archetype”: tanks hold the line, casters kite and keep their spacing, assassins dart in and back out.

# – Behaviours are stacked like ingredients, so some girlies can learn to flit and wander with the right skills! (hello, fantail).

# DRIFTWOOD REWORK

# – Her whole kit has been moved onto the shared combat tech and cleaned up.

# – The SPLINTER status has been removed entirely.

# – Splinterback now acts as a simple damage reflection, Rot is now a self-cast AoE Rupture, Drift has been simplified, and a new Bonded tether lets her share a single life pool with an ally with SOAK.

# – She’s now more consistent, less conditional, and her skills actually function as they say they should, because…

# – Done a big backend pass on statuses, equipment, MP, HP and regen.

# – Skills should be more robust and predictable. A few numbers may feel a touch different. please report anything that feels completely wrong.

# Foliage & wind

# – A new entity system built across town, home, the coast and the Tangle: plants, trees, rocks and debris all slightly more optimal.

# The loot table for several zones has been updated, with more equipment drops.

# Finding Taerin in cages and dragging them home… now actually brings them home!~

# Generally optimized the system so it should actually do what it says its doing.

- –Schist –a pile of rock
- –Pohutakawa –big red south pacific christmas tree
Each have their own full portrait sets, variations, overworld sprites, combat animations, species sex actions, and combat skill tree. And they’re ready for you to find them in the wild~!
futa cosmetic variants have been added for all species. (Excluding NPCs)
- -these can be toggled ON/OFF in options, and % encounter chance can be set to find them in the wild.
New NPCs have moved into Haven~
- -Tieke, with her board of favourite things.
- -Hiwa, a spotted kiwi who trades in secrets.
- You may find weird, cryptic ALL-IN-CAPS text in the world. These are secrets, and if you tell these to Hiwa, she might give you something in return~

NEW MAP

Wilds_02: Coastcan be accessed after completing quest005.
- -Map includes variations during day/night time (high and low tide) for even more explore!
- -Most new species will show up here, depending on the time of day.
- -Two quests can be found here.

OUTFITS

A wardrobe system has been added.
- -Maxing out a girls affinity for you lets you take everything off!~
- -New outfits can be unlocked via quests and codes.

NPC BONDS

Each NPC now has a bond track that deepens through quests and interaction… More coming soon~
- -For now, it’s a way to repeat sex-scenes experienced though quests.

xxx/LOVE

-Multi-partner love scenes added. A second girl can be pulled into your mischief~
-Species personalities plays a more significant part in some sex actions (system is incomplete. It is being rewritten… slowly~)

AUTOSAVE

On day advance, the game now makes a backup save.
- -Up to three saves can exist, before they begin overwriting each other~

COMBAT:

combat abilities and passives separated into proper systems.
AUTO mode available permanently in options, combat can be toggled between manual/auto/and whatever-you-used-last.
More combat orders added, and some rulesets tweaked to prevent dead-endsetups.

OPTIONS:

TABOO content filter added to options to mitigate some of the bodyhorror & bloodplay.
- -content filtering to be updated as people continue to send DMs expressing their disgust and outrage~ 🙂
Graphics options:
- -vsync, framerate cap, shadows, particles, shaders, combat vignette.
- -If you’re playing on MAC+WEB, probably best to play in full screen, and make sure combat_vignette is off.
If you’re on web, you may need to clamp framerate and toggle off shaders. Web functionality is hard to optimize for…

FIXES:

Lots of fixes. But highlighting the ones that were brought up publicly!~:
- -fleeing now disengages enemies properly, and supporting characters will not immediately reengage in combat.
- -fixed issue where fleeing or re-engaging in combat could teleport users to 0,0, and cause a softlock.
- -fixed several quest steps that could become permanently inaccessible if the player just mashed through dialogue too quickly.
- -fixed simultaneous KO/Softlock if the taerin wanted to the captured.
- -quest001: fixed an issues where dying would skip quest progress and lead to softlock.
- -quest001: fixed the sandslime who could brick the game 15 seconds into a playthrough, by wandering too far south.
- -quest004: added quest markers to barricade objectives.
- -quest005: Massively reduced the difficulty of the mandatory fight. Added passive healing to the campfire so suboptimal builds can still progress the story.

Developer Notes:

Kia~ Solo game dev getting their feet wet in this big wide world… Right now I’m here to make adult games about cute bird girls and other stuff I think is neat.

Cheers for checking out the page! Let’s see how this goes!

Unique, Customizable Monster Girls

Inspired by the ecology of New Zealand (though… yes you will still be able find your favourite basic-bitches like cats and rabbits here too…) Each girl you can catch is her own species with her own Goddess, her own traits, personality, visual features, and sex options!

Active-Time combat, where everything is capturable!

Every species also has her own attacks and abilities, her own archetype, and her own little tricks to make exploring the wilderness an adventure!~

Bond, Cleanse, and Corrupt…

A nameless corruption lives inside every girl… Bring her home with you, and explore a hundred options to wrestle her mind back from the dark! Teach her what love looks like… or don’t! Maybe you like her better as a pink-glowing-eyed abomination~

A thousand different scenes~

A deep dynamic text-based sex system that changes every time you engage with it. Choose how you want every scene to play out. Different personalities, different species, different routes… Your girls will evolve as you do — or more like… as you screw.

A living temple that runs while you sleep…

Taking your girls into the wilderness is only half the fun. Give your girls jobs, listen to them gossip about each other! Check in with them each night to find out what’s changed!

A campaign!

Every new update will bring more adventures, more girls, more quests and romanceable NPCS, more places to explore… and more secrets to uncover about the world…

A world that is specifically Aotearoa, New Zealand.

It’s a bold claim to say you might learn something in a porn-game… but this one’ll teach you a thing or two! Impress your friends with your newfound knowledge of obscure New Zealand birds, plants, myths and legends~. If we get enough support, maybe the government will even put this on all the school computers, so that everyone can learn along with us!!
