- Curious, this sounds like local machine slowness. Undo is basically instantaneous under the hood, and there's a quarter-second screen wipe effect for fun, but you can mash "undo" as much as you want and it interrupts the animation so you don't have to wait. On my laptop and Android phone I feel no slow down nor have I heard of this from anyone else who played the game.
- Fair point. On a keyboard you can just hold the Z key and it zips back pretty quick. Less fun on mobile since I didn't implement repeat on the touch controls.
- That may be a convention but it was a deliberate choice not to implement it. I was inspired by Void Stranger which does not have an idle. At least in the levels I designed, I tuned the timing so if you do the optimal solution there's no time spent walking into walls.
Thanks for the feedback!
