Great game! The Gameplay is fun and the art style is cool(although I think the pixel art is too high-res. You should be going for lower res or a hand drawn style. Now it seems like you couldn't decide between the two and you picked something in the middle of that. And you should keep texel density(I dont know how its called in 2d)in mind) . The Feedback when an enemy gets hit isn't there. Thats really important for the feel of your game. some Particle fx or a flashing enemy would have been great. Second best game I've played on this jam till now
If you have had one day more to polish the game it would have been just perfect. 4/5
