Mouser — About this game
Mouser puts a cat at the foot of a house where mice have taken his sweetheart. Catching blue mice supplies the missing ladder needed to reach the upper floor, so simply climbing as high as possible does not complete the rescue. Hostile mice throw objects across the platforms, making jumping and a clear route between ladders essential. Fish provide an extra scoring opportunity, but the main task remains catching enough blue mice and reaching the captive at the top.
