I played your Terry The Skeleton game a few days ago. I thought it was confusing and frantic with the flashing bar and everything. I like this approach much better.
For controls, you've got it so that action button toggles between step and dash modes. I'd like an optional feature for a hold-to-dash key, like say the shift key. So in that mode, arrows would step, and shift-arrows would dash.
Just now got this error:
