https://github.com/djblue/tetris/blob/master/src/tetris/core... to update the mapping :)

I was following https://tetris.com/play-tetris, but I would be down to change it. It messes me up when I use the HJKL mapping.

I really appreciated that it followed that convention because I was used to it. Also remembering 2 buttons (rotate and hold) makes it harder IMO. Being able to use up for rotate means I can just keep my finger hovered over the hold button. Then again I'm not much of a keyboard gamer.
