Soundwave Shock

Soundwave Shock is a Nine Circles level by MachineGun.

It was meant to be his hardest level yet, but it was never finished. However, recently MachineGun has thought about reviving it at some point.

It is a tiny level being only 9 seconds long and having 946 objects.

In its current state it would probably be Hard Demon, but if finished it would be Extreme Demon.

The song is Viper by F-777.
