I loved that game, everything was good, the art, the music, it all fit so well.
I especially liked the fact that you got the gameplay loop of a good platformer done so well with various mechanics unlocked along the various level and enough content for a while :)
If I could be a bit annoying and cite a downside, it would be the lack of key rebinding which make it a bit hard to play on non regular keyboard.
Anyways, had fun, good jam!
