Interesting idea to make a platformer that differs in the time periods. Although encountered a bug and could not switch timelines anymore

Cute little platformer game. But I ran into a bug—when I changed the timeline, it seemed like I was still stuck in the same one, so I couldn’t progress.

Hey! It crashed, but the first steps (at least) showed a clean project with a clear idea, it's a shame I couldn't play it further.
