It's a beautiful game very original and impressive art style :) I like the music, too - very nice to see that you had your own composer as well! A bit strange how it fades in and out with changing the scenes tho ^^
I am not a big fan of the gameplay, it feels very slow and the pacing is a bit off - it doesn't feel as rewarding as it could, which is a bummer since the environments are so nice. I want to experience the story but the game wants to challenge me with some very narrowly balanced platforming - fells like you are right in the middle of the two sides and the hybrid did not quite work (for me!!).
The flying also has this problem in my opinion. I think a more generous (no pun intended xD) flying would have been nice - right now it breaks with the rest. The duration is so short and the controls are not snappy enough for the duration :(
I was also a bit hung up on the early level design - especially the first door haha did I miss the interact prompt or is there none that tells you tu use "Z" - that is the danger zone of losing players in the first minute if they did not read through the controls on your page.
Its a very cool package and a jam game! I am sure you have learned a lot and hope to see more of what your team will be making in the future! Keep it up mates - gonna go pet my cat now :)
