Builderman

In-Game Behavior
Builderman smashes players with his mighty ban hammer! The deadly whack instantly kills players and creates a circular and flat, expanding "ban wave" that grows on the ground for quite a while, which should be long enough to extend across the entirety of every level in the game! The ban wave trips players upon contact and notifies Builderman to target them. Builderman also has another ban wave attack, where he summons a tidal-wave like ban wave that travels forward briefly then shrinks down afterward. The ban tidal wave still has the same purpose, but it can push players unlike the circular one.

If you are targeted then killed by Builderman, you will become "banned." Banned players respawn as guests, which they lose everything they had before banishment. You stay banned until the next round finishes, unless you get banned on the final round of a level. You will regain everything after getting unbanned.
