//So how this is planned to work is it is an item that allows you to fly with some interesting movement mechanics.
//You will still move instantly like usual, but when you move in a direction you gain "momentum" towards that direction
//Momentum will have a maximum value that it will be capped to, and will go down over time
//There is toggleable "stabilizers" that will make momentum go down FAST instead of its normal slow rate
//The suit is heavy and will slow you down on the ground but is a bit faster then usual in air
//The speed at which you drift is determined by your current momentum
//Also, I should probably add in some kind of limiting mechanic but I really don't like having to refill this all the time, expecially as it will be NODROP.
//Apparently due to code limitations you have to detect mob movement with.. shoes.
