Really cool take on the theme, as others have said. The art design is really awesome too with the high contrast and simple-tone pixel aesthetics making things stick out. Once it clicked and I figured out how to work the rotachine, I quickly got a grip of things.
Somehow managed to time travel backwards to the start accidentally, backtracking instead of taking what I assume was the intended path. Even then, it was really fun.
I think music would've helped improve it all, but the core game loop and mechanic were really solid, and for something made in two days it was well put together!
