Description from unMAMEd : "You're a car that stomps your enemies. The floor is filled with blue, red and yellow tiles. Different points are added depending on the tile color. Sometimes a tile changes to a hole, and you lose a life when you fall.". I admit it's pretty hard to tell what's going on, the port doesn't have the best graphics. If someone does bother bringing this over, this is definitely something that could be improved!

Here's an obscure one on the Sord M5. Wonder Hole. It's a port of an arcade game that's never been dumped.
