All instructions are in the game. Make sure before you let go of the duck key, you are fully clear of anything or you could get stuck in a glitch. However, pressing "r" should reset the level.
All levels are tested and possible. Backdrop colours are random. Sorry if the ending seems strange, couldn't think of another way to end it. Credits: @griffpatch_tutor: platforming script (mostly all of it) @amy482004: rest of coding and art
