Rollback to January 5th version

Hi Folks. My apologies, but I had to roll the game back to the January 5th version.

A player discovered a bug in the new undo system (thanks Diane!) that allows you to cheese every puzzle in the game. So for now the restart behavior will remain destructive until I push the update that fixes it.

I'm planning to release a major update this week, just before my upcoming heart valve procedure after which I will be temporarily unable to work on the game (1-2 weeks of down time).

It will have volume controls, steam cloud support, and a fix to the bug Diane found.

Thanks as always for playing, and don't hesitate to reach out if you find any other issues.
