The very Antithesis of a platformer. Use anything but the ground to make your way through one long level. W to jump A/D to move sideways S to fall faster R to return to the previous checkpoint Minimize Deaths/Restarts [xR], Jumps [xJ], and Frames [xF] for extra challenge.
All code was written by myself, with no outside help or looking at existing code. As such, this code is most likely extremely bad and inefficient. However, it was fun to solve the assorted problems posed, and it works, so I believe it's a good enough system. Please remember that this is a demo. When this is released as a full game, the level design, sound, and graphics will be polished. Inspired by a section of Darker Side in Kaizo Mario Oddysey. You can see a playthrough of that section starting at 22:00 in this video: https://scratch.mit.edu/discuss/youtube/L0Hq6BC_oFA/
