I like a lot the monochrome graphics in this, the game behaves correctly, the mechanics are nice and we can even use jetpack that helps a lot, the feel of being in the outer space is great in this game, boss fight is hard but manageable.I could maybe advice you show some particle on ground when we jump but well its really cool as is, the animations are cool. I rate graphics, fun, control and music the most, but all is great really, also, if you have some time, please, rate my game too, thanks!!!
