Uh.... a bit scuffed doodle jump.
1. Movement cap is weird. Acceleration is weird.
2. The way you handle the jumping + platform checking is not ideal: when I move into the platform from the side (also happens when I have the jetpack toothpaste), I just repeatedly jumping into it for a while. This would have been avoided if you use a raycast to the ground to check for platforms.
Gud sound FX tho, match each other and the art style.
