Wonder Project J: Kikai no Shounen Pino

In this simulation/role-playing game, you must use the robotic pixie Tinker to educate a robot boy named Pino. You can move Tinker around, examining objects and collecting them in an adventure-like fashion.

Pino will automatically follow you to the direction you are facing, but will continue walking until you stop him. He will also pick objects and make his own "experiments" with them. Your goal is to train Pino in various disciplines.
