Move with ARROWS / WASD.
Eventually, attack with SPACE.
Eventually, dash with SHIFT.
Rewind time with DELETE.

I should have learned from last time that time reversal takes bloody forever to implement in a jam. I thought because I did it once, it would be easier this time! Nope. I really ran short of time on this one as a result, so the theme doesn't really come through at all and I didn't get to explore nearly as many puzzles as I wanted to. Oh well, I think the concept is cool!
