Cool game, I beat all 10 levels. How exactly does "not seeing your splits" make it harder, it feels the same.
Some people would rely on being able to see their splits to time the next double jump perfectly and get 1000 score. Also, since this was a 48 hour Jam I was really limited in how many mechanics I could introduce while keeping the game mostly bug free. I do agree though that it's not a major difficulty spike.
