Use Nothing ! Save the Factory

Use arrows to move around.
Use left mouse button to create nothing. Hold for a larger hole.

The goal is to have three bots of each color available.
There are only three levels.

The Nothing can block lines of sight but also kill anything (even you) as long as the hole is wide enough to swallow your target.
Bots will find the nearest visible Diamond if they dont carry anything.
Be careful as they move faster when holding a gem of their color !
