Hey, the game looks cool. But I see that you didn't have much time. But you'll get used to it soon :D
I have to create my game in just 2 days from this jam bcoz of exams. Anyways, the only feedback I have is to add some background effects or maybe a particle effect to make it look good and also try to create a very short tutorial. Also, bump down the resolution size. This was indeed a great game. Please don't forget to checkout my game and rate it.
