Thanks a lot for your feedback and playing the game. It's true, the jump controls are indeed very rigid, I wanted it that way so that you have very precise control over the player.  But yeah, you have to be very patient at the beginning.

That's also true. I wanted to make a little tutorial stage and probably I could manage to do that in the last two hours, but unfortunately I was super done and so I called it a day.  On top of that I totally forgot to explain in the description how to use the switches, but I edited it now.
