Interesting idea. Though you can just keep multiplying you score by warping back to back. The game doesn't give you warp damage when you keep just holding D and falling.
Hmm... I made it so if you do 3 or more screen wraps in one leg you start taking damage. Also you have to jump to actually increase your score, the multipliers dont apply unless you jump.
You can clear the platforms and then just keep going and falling. And since the screen warp damage count gets reset on direction change you can do it infinetly. And if you store some platforms in the backpack you can then apply the multiplier.
