Changed PowerUps, (and some other stuff ngl)

Replaced 2x Speed and 0.5x Speed with:

Box Drop: Press “Q”, “U”, or “Slash” to drop an object that was held in an “inventory” slot in front of them. (i.e. SpeedBox, BouncyBox, PowerUpBox, etc.)

Death PowerUp: When the player dies to a DeathBox *not to falling into the void* there will be a pop-up that will allow the player to select any PowerUp of their choice so when they continue the run, they will have that PowerUp, and the DeathBox they collided with, will disappear.

I also made some other small changes.
