Lockjaw: The Overdose

Lockjaw: The Overdose is a freeware Tetris clone for GBA by Damian Yerrick.

At first, the gameplay of this clone isn't anything different from other Tetris clones, especially The New Tetris. But after playing for a while, the playfield starts shaking and distorting, hence the name. It was previously known under the name Tetanus on Drugs, until July 22. It's predecessor is Lockjaw.
