I think the idea of the game is really cool. The main piece of feedback I would give is that, and maybe this was just me, but I feel like the platforms should be a bit more distinct from the background. On the first level, it took me a while to realize that the platforms on the left weren't part of the background and that I could actually stand on them. The idea of having your past selves help your present self is a really cool idea, and your implementation was great for the time restrictions we had this jam. Nice game overall!
