It's a very barebones game beyond the novelty of having these characters in one place and in a supposedly-impressive handdrawn style that kinda gets ruined by everyone who's not ripped from Terrordrome being animated like the "bowser fart .gif" - in less crude terms, janky puppet rigging. Just about everyone explodes into the same cartoony-looking skeleton gib animation when they die (yes, even Gizmo and Eleven). Speaking of Gizmo and Eleven, they nearly trivialize the gameplay because Gizmo can use a secondary, stronger shotgun blast with the only penalty being a bit of lag and Eleven feels like his gameplay is just "projectiles: the character".
