Asteroid Invaders (itch) (J̷̻̇a̷͖͝s̷̭̿o̶͔̕ñ̴̞)

Asteroid Invaders is a spin-off of the classic arcade game Asteroids. It introduces 8 different play modes, one of which is the classic game, while the other seven alter your gameplay experience, like shooting for example. The different mechanics arent explained, however. This may seem like an oversight because I only have four hours left, but nooooo, this is a strategic and totally intentional decision, to challenge you to figure out the mechanic before you are utterly crushed by the asteroids!...
