Wonderful game!
I like how it looks a lot. There is variety but maintaining cohesion in the art.
The game mechanics fit perfectly with the jam theme. And the controls respond very well.
It's hard, but very fun, I wanted to continue playing after losing. Maybe the first levels could be a little easier.
The game froze several times. Some because I accidentally hit another key and sometimes for no reason. That was annoying, but it sure is an easy bug to solve. That would be my only complaint.
Good work! Congratulations!
