Love the art style so much! Your game's thumbnail was one of the ones that really stood out on the submissions page for me and I was excited to play this.
The game definitely induced some "arghh godammit"s from me, but I ultimately felt really compelled to get through it and finish it, so well done for that. I'm not really a fan of rage games, so I think the fact that I finished all the levels says something about the excellent quality of this game. Well done! And also, F U!
