What does it change?

I publicly shared a Steam controller layout for XBox 360 controllers. I hope it's helpful to other players.

For some reason my game speed feels slow, it's slower than the first video on Steam store page, and the movement input also feel sluggish.

What are the controls? So far I have only found arrow keys for movement, space for jump, A to cast some weird magic and to confirm in the menu, P to skip intro and cancel in the menu, arrow key down + A to open the '?' block.
