I totally agree and would also love to put in a "one step back" feature. Unfortunately that is one of the features I couldn't implement due to my lack of technical knowledge. I'm hoping someone tip me off to a simple solution during this gamejam.

This game has a replay mechanism, wondering if it can be jury-rigged from that: https://itch.io/jam/gamedevtv-jam-2022/rate/1554340 another one that does this is https://itch.io/jam/gamedevtv-jam-2022/rate/1550919 ... Both use the system for other means, but you might be able to build something that allows you to go back a move.
