Yeah, that was the original idea - I wanted the levels to load in order to make 3 long levels instead of several shorter ones. The intent of the loops was to add a few new obstacles to each 'biome' to build up each loop, but it was probably too difficult to tell with how short and crowded the levels were. There is actually a button to move forward a step! It's the 'enter' button, but on the rare occasion it causes crashes when an object moves by too quickly and doesn't despawn properly, so I didn't mention it on the main page. Maybe I should with a warning?
Thank you for the constructive feedback! I'm really appreciative people are taking the time to play my game and leave it, so I know what I can do better for future jams :)
