Fantastic game. Probably one of my favorites in this jam. I certainly spent the longest time playing this one. The art is absolutely adorable, the gameplay is fun.
All it needs is some polish here and there and you have a solid game. My main gripe would be the flies. Their fire attack felt unpredictable. Most of the times when I took damage it was from them, and it didn't feel fair. I didn't feel like it was my fault. I would maybe only have them attack whenever they're onscreen, and give them an anticipation animation. So the player can see when they're about to attack. That or slow the projectiles down by a lot.
