Nice game!  Here are my observations: I had a hard time figuring out how to leave the first level - but realized that you have to exit under the arrows. I like the music! Will you be expanding on the game after the jam? 

Video Commentary:

Nice one. I love that you allowed players to simply choose which level to play from the menu and included lives, those kind of accessibility features are great to see in jam games, especially for players like me who are terrible at 2D platformers.

The artwork was a little inconsistent. Different pixel sizes, some objects had black outlines, others white, some none at all. Some consistency would go a long way towards the game's polish.
