This is a neat concept and very ambitious for a jam. Playing with time has a lot of potential in a puzzler.
Unfortunately, I'm too stupid to figure out the first puzzle with the three switches.
I did keep encountering a breaking bug that you might want to know about. If you stand on a platform and rewind time to a point that it's no longer able to step onto, you get pushed off the platform into the water and then can't move anywhere
Of course, this kept happening right when I thought I had the puzzle figured out. You did manage to stump me, which makes it a pretty good puzzle. But it might be a little difficult for the first challenge - but I won't rule out that I'm too stupid to play
Good game!
