Aah yep I played with keyboard for this one, I find that most users either go for WASD and the mouse buttons along with shift/space just because people are used to using fps controls.
There are a large number of games that also go with the arrow keys and ZXCV (usually towards the CV end if there's than 4 less buttons), occasionally using asdf for side things that arent used often. I personally prefer this one myself.
Thanks for downloading my one too!
