What is the game called in which a spaceman dressed in a purple suit jumps around on courses trying to find jewels and keys and shooting space monsters such as space bats and space snakes? I think the spaceman has yellow hair and wearing a helmet with a light and he has a laser gun. The game has a lot of bright colours.

What machine did you play it on?

I think you may be asking about Blasto on the original playstation. If it had a zany voice actor its almost certain.

You may remember the voice actor (Phil Hartman) from such films as: The Three amigos, Fletch Lives, and Kiji's Delivery Service.

Or such televison programs as: Magnum P.I., Duck Tales, and The Crittic.
