Ruff and Reddy in the Space Adventure is a computer game based on The Ruff & Reddy Show. It was released in 1990 for the Commodore 64, Commodore Amiga, Amstrad CPC, Atari ST and ZX Spectrum. It was developed by PAL Developments and published by Hi-Tech Expressions.
Due to an accident involving Professor Flipnoodles' Pocket Rocket (would you trust a scientist called Flipnoodles? Most people wouldn't, especially as mad scientists cause so many computer game plot disasters), Ruff and Reddy have been hurtled into space. The Lilli-Punies have kidnapped them, and will let them free only if the heroes can rescue their missing compatriots.
The search starts on the surface of the planet, but later takes Ruff underground into the cavernous regions the Lilli-Punies inhabit. These have lots of water, which Ruff must avoid. Plenty of extra lives can be collected along the way, with puzzle-solving ability as important as good reactions and dexterity.
