I have something similar in mind too! Although in my opinion R/F for going up and down will be better for this scenario. I think Q/E most often associate with rotation in this kind of camera perspective.
Hey Geoff! I updated the game, it now has keyboard controls! I thought Q/E worked well for me, but I also added R/F to go up/down as you suggested. Let me know what you think if you give it another try :) Thanks!
