Yes we had really amazing 3d artists on our team i'm impressed too ! The cat was definitely inspired by the Cheshire cat so you spotted right !
The feathers system is indeed pretty useful for escaping the maze, i'm usually not a big fan of maze but I don't find this one exhausting to navigate in thanks to this system and the different "biomes" of the maze. Like you said our composer was amazing too (in fact all the team was really it was such a cool experience). That's really cool that you've seen a duality beetween the night sounds and owl sounds, that's a really good reading imo.
And by the way the credits menu is now fixed ! But you can also find the credits in the game page description !
And we will try to make it easier to see the exit too if we have the time.
Thanks for this nice and complete feedback !
