Click the green flag at least twice. Arrow keys to move. It has a few bugs. Level two/three is the hardest. Features; Ceiling detection. Harder than my intermediate and basic level platformers. No scoreboard or world record. (This project is meant for fun). Ball character (hitbox is not confusing). Free remixing XD. New; Bounce pad (red (bounces you higher than you jump)). Death pad (yellow (makes you restart the level)). New levels (duh). Your jump height is decreased, due to a cheat in level two.
Credit to @110percent for the jumping script.
