WARNING:
Google Chrome has a built-in Flash Player, and ever since the new update causes a sound glitch to happen. Before the update, it never occurred, yet it's the SAME file. Honest. Newgrounds has also noted other problems with the new Chrome update regarding Flash: http://www.newgrounds.com/bbs/topic/1265535
So... you might want to use a different browser until Google fixes this, unless they're too busy figuring out what the hell to do with G+ now.

EDIT: Issue seems to be fixed now. I did nothing.

Mind-bending, Space-rending, and Completely Innocent Creature's Life-ending.

In this negative-space puzzle game, you'll drag around holes, fall through walls, and bring myriads of miniature Monsters to madness.

Say you sadistically hunger for more levels, or you just detest the levels I've made. That's fine, you can play negative-space puzzles created by other Newgroundians! And you too, can make your own.

Use the Level Creator to design your very own puzzles, and share them with a cold uncaring world. More Monsters to torture, for the good of everyone else!

Think outside the box, fellow monsters.
