I would recommend space for jump, as most games allow for this and Z can feel quite strange. R for reset is a pretty important key (when I eventually understood I had a limited scaling ability), but wasn't listed as a control.

Wow, I feel a bit dumb-founded, I forgot to add R for reset to the tutorial level XD
I was also planning on using a feature that used the X key so I thought Z made sense, until I didn't Lol, I am planning to change it to the space bar after the jam is over, or I'll add a use to the X button. sorry for the inconvenience. I'll try to update the game after the jam to use spacebar instead of the Z key (This seems to be a very common recommendation), if you find anything else that you think should be updated, feel free to tell me!
