This game gets full marks from me! You have incredibly expressive pixel art and great game feel. I particularly like the effects you have on charging, hitting the boss, and both the game over and win screens! Each boss is unique and you really embraced the theme with rotating the stick. I also really love seeing more Unreal games in jams!
One piece of feedback, I think the second bosses attacks come out too fast. This one pictured in particular. I'd love if the hand lingered just a fraction of a second longer before it hits so you can react better!
Outstanding job!
