It wasn’t any of those. It was just a simple interactive game. It looked like a kid did it in MSPaint. I’d draw it, but I’m no arteest.
New Detail: I remember now, if you clicked on a drain in the bathroom, the alien would comment “It’s really dark down here” in a bubbly sound.
The alien: I think it started with “M,” he was short, green with spots, had a red nose, and two antennae with purple at the ends.He had a light green belly and children’s hands and feet.
