In ULTRAKILL you can:
Punch your own bullets
Shoot coins so your bullets hit enemies automatically and deal extra damage
Parry a giant corpse
Give a giant robot a lobotomy
Slide down the great pyramids of Giza while fighting a red go pro
Get obliterated for 2 hours straight by Sisyphus himself
Spin a revolver to make it deal more damage
Make a rocket launcher shoot cannon balls
