Maybe I'm being big dumb, but what's the solution to the 3 stone puzzle?

I'm unable to enjoy games with the default (WASD etc) controls; is keyboard rebinding available/planned?

Would be really neat if you could add some.

Where are the Black Rocks?

I watched your Youtube video, looked closely at the game. You'd have my £0.77 (what I have in my steam account) right now if you'd discounted a bit more. Oh well, I'll save up my meagre cash-outs for another day.
