Have you ever played this game that was in a pirate GBC game called 14 games in 1!

It's a small robot that shoots dots at a another replica of the robot and when it shoots at the robot, it automatically dies in one shot and then it goes to the next level.

It was more like a space robot with chip sound. Another thing is in the game, the ground is made out square small block, so when you shoot the ground, the block would be destroy and you can make a hole on the ground.

The robot in that pirated GBC game just look like this one here:
