Evolving Valley
Above these vast lands, a rift has formed in the sky. Many individuals intend on visiting here, whether to investigate this anomaly or otherwise.
Choose the order that these people will arrive, watch them interact as the land transforms them into pokémon, and discover the ultimate fate of this land.
Welcome to Evolving Valley.
~~~~
This is a transformation themed Twine game, intended to be played multiple times in search for an optimal ending. Contains 8(?) pokémon transformations and more than 14k words of story to uncover.
This game features transformation into pokémon, as well as varying levels of mental changes. This does not require much (if any) pokémon worldbuilding knowledge, but some familiarity with pokémon species is preferred. You have been warned.
Other Notes:
- This is 100% a ripoff of the GROW series games (eyemaze.com) in terms of concept; take that as you will.
- "SuperOmegaSpoilers.txt" is exactly what it says on the tin.
- Using autoskip might result in quick-flashing visuals. I've tried to fix this, though it seems incompatible with what I want from the feature.

I love how well thought out the game is!
Spoilers, but here are the notes I've taken on the game
I haven't been able to complete it, but I'm determined!
Arthur the Adventurer: Chuck gives him a sword if they are both in the camp; then Arthur will go out adventuring before reappearing as Sir Arvine the Serpentine Knight the next day. Carmine will give Sir Arvine a potion if they are both in the camp. Then Sir Arvine goes out adventuring and disappears for 2 days (will be revealed to have transformed into Serperior, the Self-Proclaimed Tyrant)
Carmine the Chemist: uses 3 "wagon full of berries" to make each potion, has Rohan go get seaweed; after 1 day with the seaweed, he'll become 1/2 transformed; after 1 more day, he'll fully transform into Octillery the Mix-&-Match Multitasker (unknown if blocks interactions)
Chuck the Craftsman: after giving 2 items, he'll become 1/4 transformed, giving a 3rd item and he'll become 2/4 transformed (unless missed), when the orb is collected, he'll become 3/4 transformed (2nd and/or 3rd items can't be made if the orb was collected before them) and the orb will be cleaned, after building the rift spire he'll fully transform into Tinkaton the Stone-Forged Menace before leaving the camp (unless other items missed). Can feed Meowstic food scraps.
Rohan the Fisherman: Chuck gives him a better fishing rod if they are both in the camp which allows him to catch 1 fish every day, after 1 day with the fishing rod he'll become 1/3 transformed, after another 2 days he'll become 2/3 transformed, Meowstic can steal a fish from him before it can be counted to the inventory (only if she's healed) if Sir Arvine is missing for 2 days he'll go look for him and go missing (if 2/3 transformed he'll find Serperior and be given a stone tablet, as he returns to camp he'll fully transform into Eelektross the Sea Monster, he'll leave the stone tablet and disappear into the sea) (he'll go missing 1st if it's both the day he becomes 2/3 transformed and the day he looks for Sir Arvine)
Julia the Forager: becomes a Noivern after 6 days (including her 1st day in camp) and won't be able to do her interactions with the others, Chuck gives her a wagon if they are both in the camp which allows her to add 1 "wagon full of berries" to the camp's inventory (even as a Noivern after 1 day of no berries), can find the rift's location if Simon (unless fully transformed) asked to go map the area out, Meowstic can beg Julia to go hunting with it (only if she's healed) (they will go hunting the next day)
Evelyn the Mage and Meowstic: Meowstic gets sick on its 1st day (unless it's day 8) (Carmine can give a potion ONLY THAT DAY to Ivory to help heal Meowstic, but that ends up with Meowstic turning Evelyn into another Meowstic as revenge for emotional neglect... (Sir Arvine's potion event will always override it), Evelyn (even as Meowstic #2) can gather Julia and Chuck to go build the rift spire if both the rift location and the cleaned orb are in the camp's inventory
Simon the Researcher: Becomes Galvantula the Cave Matriarch at the end of his 2nd day in camp; will have Rohan go get an orb if they are both in the camp (can't as Galvantula)
Ivory the Pokémon Medic: can mostly heal Meowstic if they are both in the camp (gets hurt when potion is used), will check in on Simon if they are both in the camp (gets attacked if Simon is the Galvantula), will try to check on Eelektross before he disappears, only to get hurt. Transforms into Mismagius, the Spectre of Nightmares, if hurt 3 times
3 things are needed for the optimal ending: Rift Spire, Meowstic Duo (former owner Meowstic and original Meowstic), and stone tablet
There are 8 days before the game ends, each allowing 1 character to join camp
If I got anything wrong, please tell ^^
Semi-spoilers (vagueposting):
I haven't looked too closely, but other than maybe one or a few things missed or wrong, this should be mostly accurate. You should be close, if you can put the pieces together... :)
I got so close before giving up. was one swap away. Berry picker is cute throughout though. Definitely my favorite character.
Hey uh, I noticed something that seemed a bit incorrect in the story. (spoilers:)
I think you mixed up the meowstic genders in the evelyn's scene after her former pet got given the potion? like i checked some pokemon wikis and stuff just to make sure, and the mainly dark blue meowstic with the white fur tips and blue/green eyes are the males, and the ones with mainly white fur and blue fur tips, with red and yellow eyes are the female ones? like idk if you just mixed them up, or if in your world its in reverse colors compared to the official pokemon designs, or if the meowstic also swapped the genders of both of them when turning evelyn or something? just wanted to ask. or maybe i misremembered evelyn's pet being darker blue? cuz i played again and now its definitely a girl meowstic,so i'm not sure if i just misremembered, or maybe the gender is random, or what?
Spoiler wall:
The pet Meowstic is female. The Meowstic that Evelyn becomes is male. Not sure if that answers anything or 100% matches the text, but that's the intent.
Grow Island and other games were my childhood, so it was great to play a game inspired by them. Almost got the True Ending myself, just couldn't figure out the mage placement.
Also, the secret ending is funny, meow :3
meow :3
I really like the transformation progression! And thanks for having the spoilers, that helped
