Saru Ga Daisuki

Saru Ga Daisuki is a platform game where the player controls a ninja monkey, out to save his girlfriend from an evil doctor. The monkey can run around, jump, and cling to walls and ceilings freely; it also has a weapon in the form of a yo-yo with which it can destroy green blocks and flip switches.

Completing the game requires getting past several rooms with classic platform game threats: spikes, cannons, flames. Some puzzles can be solved only by switching to another character and using their skills (e.g. a fast, high-jumping ninja). Sometimes, items have to be used, such as a water-spewing backpack that can put out flames.
