Considered the worst commercial game for the ZX-Spectrum. After breaking up with publisher, the author was forced to deliver one more game just to fulfill a contractual obligation, so he developed an intentionally crap game to ensure it would be discarded. It wasn't.
The game cannot be controlled due to the fact that CAPS LOCK is turned on. In order to play the game, BREAK into BASIC and issue POKE 23658,0 and CONTINUE.
