The annoying thing is that the guy rotates when you're holding down to jump. So if I want to go to the right, I have start facing to the left and then hold down 1 (turning me and jumping).

Very nice! I completed it in 00.44!

Really cool and original idea, good job! The art is very simple and minimalistic, which fits perfectly with the "only one" theme, nice! As others have pointed out, it is pretty annoying when you have to restart the entire game when you die, but otherwise it's a fun game! Well done! :D

Like edmond00 said, I also would really appreciate checkpoints.

Very original idea!

I is a little annoying that you need to restart from the beginning when you die, I would like to have some checkpoints. Also, it is a little frustrating that you collision box change when you are only rotatin as sometimes you manage successfully to jump on the border of a plateforme but you still die you because the rotation make you fall. But otherwise it is a nice little game fun to play and I liked the minimalist aesthetic.

Interesting. Not very happy when I jump into another screen and there is a pit waiting for me.It feels unfair to me. 

Pretty nice, I think it would be better if your character stopped between the screen transition so you don't fall into a pit you didn't know was there!
