Haha I feel sometimes I am not sure if I am solving the levels the way you intended, but I make it look awesome by giving them -9, -7 and -6 speeds! Really nice idea for the Jam and very original, I had a lot of fun playing this one, good job!
Nice, I'm glad you're having fun! And there is no 1-intended way to solve a level, some levels have solutions that I don't even know about :)
