Drelbs

[User Summary]

In an Orwellian future, all the Drelbs have been rounded up and imprisoned for unknown purposes... All except for you! You are the last hope of your captured race, and you must break into the vast prisons and free your kin, all the while avoiding the sinister Trolloboars and Gorgolytes seeking to complete their collection of Drelbs.

Gameplay involves making squares that solidify by pushing walls, creating traps for the enemies while trying not to block yourself in, and avoiding the tanks and sentries until you can collect the key to the current level's dungeon and round up fellow Drelbs in a bonus stage.
