That's insane. I ended up giving up on floor 17 thinking that it couldn't get any harder (but apparently it did)! This game was so difficult that its creator (tasselfoot) gave up himself after playing it for over 20 minutes.
You know a game is way too difficult when its own creator gives up on it.
Congratulations. You did it I gave up at level 25. I can't play this game for more than 7 minutes because my eyes really hurt, so I know I will never beat it. By the way, nice video. Loved the last stage. Really bloody.
