Very fun and immaginative concept. I think the main mechanic of going back and forth is really interesting and well executed but I feel like it is independent from the theme. But well done!
Thanks for the feedback! I totally can see why you think so, without the animation of scaling up/down it would be outside of the theme. The best way I found to explain it is that, the player in the next puzzle is the previous puzzle, but only the color is visible.
