First of all, I'll say this: the game has a really nice aesthetic. The bird mechanic is also rather novel, and it would've been interesting to see it being expanded in a full game. One gripe that I do have, however, is that the movement feels somewhat weighty... what with the strong gravity and the decel screwing you over on smaller platforms after making a big leap.
But that's just a nitpick, I'd say.
Amazing game, i congrats you
