A tutorial level would be helpful to introduce the concept of jumping between timelines (and everything else). The UI is a bit off.
Right now, your game feels quite difficult, and it’s easy to get stuck in walls. I also couldn’t see a clear goal, which made progression even harder. You mentioned that more levels are planned, but I’m not sure the game fully fits the given theme. That said, I really like the idea of switching timelines - it’s a nice mechanic with a lot of potential!
