Thank you very much for the kind words. I was initially planning on making multiple levels with different color palettes, different obstacles and a different event at the end. This of course was way out of scope. I definetly wanted to have a cutscene of some sorts at a certain distance that would add to the story and unlock endless mode. I still didn't have the time for that and went with just endless mode.
It would be something on top of the priority list if i were to continue working on the game.
