True, If that can help a layout i like is arrow Key and Z,X,C,Shift, space. Lot of game use that. I also have see stuff like WASD to move with JKL for other stuff like map or dodge, it's rare but i found it great too .... For plateformer i personnaly don't like using mouse (exept if the game is intend to be played with it like for aiming). You can play with 2 hands on keyboard, it's not limited to WASD and around, you just need to do a tutorial for the controls (not like my game this jam XD)
