You should add a way to save a favorite stone. You would go to the stone to set it as your favorite then there would be a button to jump to the stone set as your favorite. It can be annoying to jump to the newest stone and then go backwards a long ways to a gem I want to idle on.
I don't like the controls. I know that I can change them, but it doesn't let me use my mouse for attack and I can't change things like jump/crouch to go down a platform. This game would be more fun if I could change these things.
I found a glitch. I went outside during the compromise ending, and when I came back in I tried to go up the stairs, but it ejected me through the wall. It also thinks I have already been up there, so I can't get back up.
