Hey, Andrei, great job! Submitting a game to a game jam is a serious achievement on itself! It's simple, yet catchy. I'd recommend you continuing working on it after the jam - find a way to make controls more responsive, enemies more diverse, maybe some pickups, a looping map, anything. Do not compare your game to anyone else's - just work on it, and make it better. I'm looking forward to see your games in the future!
