The art is great, and I really enjoyed lurking in the share your progress channel and keeping up with this game. Overall it came out great. Some of my issues are that some bosses are too hard. The bird boss has so much health, and the bird enemies just fly to the top of the screen making it hard to hit them. The enemies following you through rooms was very chaotic but a little annoying as that's usually something that doesn't really happen all too much in games. I also think the vertical room transitions(particularly those where you can't see the floor from the upper room) are a little disorientating and can make platforming difficult. The world was pretty, but I found myself having a bit of trouble navigating as a lot of areas looked the same, so it was difficult to find my place.
Really though that's all in line for a jam game tbh, this game is great, very much enjoyed it and the music. Nice job :D
