That's a pretty good game ! Really hard, but it managed to make me want to see more, which is a very good sign ! But my brain still cannot handle the fact that if I shoot left, I go right...
I think there are still things to do to make it more user friendly. Maybe trying to reduce the speed of the jump could help, to give a bit more time to react in case of mistake. And some platforms are at a weird height, making them impossible to jump on, but at the same too low for the recoil jump, so the level design sometimes feel a bit uncomfortable.
