Well done! In only 3 hours? Crazy! I would have lower the timer before becoming a stone/cube when you don't move. It's difficult to use the "dont move" mechanics as it is I think. Apart than that, awesome job!
This was primal to the Jam and it wasn't working on the last 30 minutes of development. But I agree with you. I put a time of 0.3sec, I should have put like 0.1sec or no delay.
