Today I've been busy. After giving up on Tinkercad's horrible exports and planning to actually learn how to use Blender, I decided to have a go at improving my original program.
I've done that. Not only have I improved the physics of the ball by taking advantage of GDScript's
lerp, or linear interpolation function, but I've also given you guys something to do, by adding 10 boxes to push into the void. I've also refined the player's hitboxes to make bodies move in a more realistic way.
