Very good. Baba is you style art. Sound, music, art all professional.
The mechanics are easy to understand and quick to implement. You don't need to think too hard while playing but there is a basic level of strategy. You will need to think ahead and decide if you really need to block all the damage. This is impressive for a game jam.
Fits the theme, does something unique, and does it well. I could see this being a much larger game.
Great job.
