Move around using your hammer, but since that's getting old, press and hold Q to use your Nimbus 2001! Also, if you press and hold E, you can open up a little menu to adjust fly sensitivity, and gravitational instability. Gravitational instability makes your gravity unstable and weird. 1.3 gravitational instability for no gravity 1.29 for microgravity, 0 gravitational instability for normal gravity, and more than 1.3 gravitational instability for, let's say... negative gravity...
The Nimbus 2001 image came from https://www.microminiatures.co.uk/product/harry-potter-nimbus-2001-broomstick/, and all i did to it was crop the feet things, and used Canva (only website with a premium white background remover that I had an account on) to remove the white background. The rest of the game is by "Gryffindor Griffpatch".
