You bet I do! Every time I switched computers, I kept it on a floppy so I could put it back on and play it once in a while. The tile used for Chip walking left or right is absolutely the most memorable image from a video game for me.

Since I know you did that, I'd like to ask something. There's a game I'm trying to remember the name of. It used tiles for graphics like Chip's Challenge, but it took place in some sort of haunted house, not only exploring the rooms but shooting arrows at monsters. The main character looked identical to Chip, but he had different hair, wore blue, and had a cape. It really looked like it was a simple recolor of Chip with the addition of a cape. Did you also do the graphics for that game? I've been dying to remember its name.
