The way the glitch works| The platformer code allows the player to, in a 71% rate chance, when you jump and your head collides with another platform or one is above the players' head when you spawn, after you move out from underneath the platform, you sink. you can fix this by in level 1 moving the platform that is above the players' head when you start up 3 arrow keys, causing the platform not to be directly ontop of the player itself. make sense? lol
