the idea of the game is good, and that it has a small story in the beginning was a nice touch. I understand it is your first time and doing it alone, and for that the presentation was actually good. It close to a space invaders, classic game. the only thing I would critic is that you die very fast since its one hit kill. maybe a health bar or multiple lives would help. but it also could be like a dark souls situation, just being very difficult. but on the whole good job for a first game on your own.
