Can't find game's name

Hey, when I was little like 6 or 8 years old, I played a game that I don't remember how it was called. I want to play it again, but I have been searching for it for a week. So now I wanted to ask. It was a game of a little purple alien that was on a seat with a screwdriver on the bottom of the seat. The objective was the unscrew all the screws without dying. There were many obstacle, but one I remember was like a cannon. I think, but I'm not sure, that the game started with the letter G or with the letters Gl. The game was on a black and white disk. I think it had a 50 on it. And the disk had many games, like the Doom 95 (demo), and other games like it. I would like to play again the game. Thank you!

its totally confusing me.

There is a 99% chance you will never play this game again

This disk in to which you say there were others games on it, was just one of many thousands of disks containing several mini games that you, me and many others, have experienced once, but now its all part of an untouchable past

Also, some things is left best with the memory than trying it again and ruining it

Sorry :(

what was it? lolmetroid5
