[4] The player controls a number of "Gruntz", diminutive, goblinoid creatures made of baked clay ("goo"), via the mouse.

The controls are those of a typical real-time strategy game: commands are issued to Gruntz via first selecting them and then either right-clicking (causing them to move or attack) or left-clicking (for special actions such as laying bombs or digging holes).

The strongest weapon is the Timebombs, which kills any Gruntz within the 1 square radius (including the Grunt himself if he's not careful).

Most weapons can be used for other purposes, such as walking over spikes, swimming, breaking objects or digging holes.

The shortest lasting toy is the yo-yo, which breaks almost instantly, leaving the Grunt little time to do anything but run away.

Powerups are collected in the same way as tools or toys, but the difference (apart from the red sparkles) is that they only last for a limited time.
