I actually really like the artstyle of the game, though at times it was hard to see enemies(for example the robots that you can get to after getting the double jump). I also quite like the atmosphere and sounds.

However, I don't know if it is just me, because I am not the greatest at platformers, especially ones with such tight level design, but this one is just sooo hard. It feels like from the very start you can't make even a slight mistake. Enemies notice me immediately, jumps are so precise I often need to try them at least a couple of times, and everything kills me in one hit. I couldn't really finish the game, just got too frustrated at some point. Then on the other hand I think if someone enjoys this sort of platforming, it is really a great game for that, so after all, nice job!
