Mouser

Mouser is UPL’s answer to Nintendo’s Donkey Kong. As the cat protagonist, you
must rescue your sweetheart from a gang of bad mice. Your girlfriend is held
captive on the top of a series of platforms, and before you can reach that
platform, you must capture a number of mice, after which a ladder to the top
appears. The mice will try to hinder you by throwing items at you; on the
first level, they throw flower pots, later on they throw spanners and bombs.
Also spread out on the levels are fish, which will speed you up and grant you
limited invincibility.
