Definitely a Suda51 game. It is so, so weird. There's a lot of little things that are very charming, and the artwork is more than a little disconcerting. The gameplay is very, very basic though. I played the entire first stage on normal and was hit once, and as of the beginning of stage 2, I have two attacks.
if ur unsure theres a demo. I just tried the demo to be 100% sure. I played level 1 on hard and while basic its fun and very werid. So far only funny thing happened was the narrator got upses with saying jump. also if your curious its only 10 bones for the game.
