[Open Assets] PiSRB2 Air Drill v1

Whilst y'all wait for MCSonic v2, I decided to dig up something from my archives that some of you may enjoy....

So, for a few months a while back, I was working on a physics mod, PiSRB2. One of the ideas I had for this mod was taking the Air Drill, a generally mediocre vanilla ability, and remaking it to be far greater than before.

I did that, and even though I stopped work on PiSRB2 (I MIGHT restart one day, since I sorta like some of what I did).... I think it's fitting to release the revamped Air Drill!

Press jump mid-air to enter Air Drill state. During this, you can either hold Jump/just pressing directional keys to ascend, but only so far. You can also hold Spin to charge a Drop Dash whilst stomping towards the ground. During all this, your speed when starting the Air Drill is maintained, allowing you to maintain speed... if you have a Momentum Mod on. You also bonk off walls, in order to prevent wonkiness.
