Dr. Brain Thinking Games: IQ Adventure

The "Buy on Zoom" link sends you to another game. It is not the same.

The link takes me to another store. Neither Steam nor GOG have this. Don't know if that's a mistake. I don't know this store, so I don't know if it's sketchy or what. Just thought someone can help me out with it.

When I was a kid, this game was really hard. I had trouble outrunning the orange two-headed mutants. I've since completed the game, and it's a good one, but it only had 15 levels. I felt that this was okay gameplay-wise, but not a whole lot of time to develop the story about the plant creatures, the mole people and the brain-sapping robots that are trying to enslave them.
