IT IS POSSIBLE. (took hours for me to test) ArrowKeys/WASD/Mouse Space is dash only on SOME levels in which it is absolutely required. R to restart. This is one of the hardest platformers on scratch. Very easy to break your wrist. 21 levels. I tested each one, and it took 1 hour for me to figure out each level. I put a lot of work into making this insanely hard. This is for platformer lovers, but don't lose hope, each level has been tested and it is possible.
DISCLAIMER: Probably not possible on mobile. :P Credits to Scratch. Art and coding is me. I didn't put a skip button because it would completely wreck the quickest time. My best time is 1403, what's yours?
