I put Math.PI/Math.E in the rotate function at the end and it looks awesome
u/ximavus

You can also change the Math.PI/3 to .1 and it looks the same but smaller

Nice mini game idea.
u/KilledByAPixel

Thanks! Been trying to get this to fit for a while until I remembered there is a trick to get the normal of a sine wave that allowed enough space to fit.
u/KilledByAPixel

As a goal to the game, try to reach the top of the dweet!
