[MD]欢乐淘气鼠

Huan Le Tao Qi Shu: Smart Mouse is a Sega Mega Drive game developed by several Taiwanese developers in some unknown year. While the name of the dev team is never given, there is a staff list - much of the staff come from Chuanpu, but there's no confirmation this was one of their products. Some of the music is also stolen from Wonder Boy III: Monster Lair, whose sound driver the game uses.

The game itself is a basic Pengo clone - the goal is to destroy all the enemies in the stage without getting hit. The A button pushes a block.
