Really polished game. Nice sound effects, graphics, and concept. The concept has been seen 10000000 times but the fact that you can move with trusters really added that spice it needed. I did 2000 points my first run and I discovered that the multishot gun is trash. Then with 28400 points I can confidently say I beat 99.9% of the player base.
Really can't give you much to work on. Maybe just add more enemies and guns but it's a really solid game already. I also liked that panini projection Post Processing effect a lot!
