It was pretty obscure, from 1983. It's a great little racer, with lots of score-depth.
I recently got the opportunity to buy the IP, and now I'm porting the game to Steam.

The company, Occidental Designs, was really weird. They made lots of stuff, but most games didn't make it out of test markets, and I've never yet heard of a surviving arcade machine. They also went bankrupt several times and pulled some wild marketing stunts.
I remember playing Bumpy Grumpy in a smokey Pizza Hut on a field trip to see the Arch in St. Louis.
The company's "history" is really interesting. You should read through it if you are into arcade lore.

I'm sure it'll jog your memory.
If you have any good stories about playing some OD games I'd love to hear them.
And do check out the full trailer, and wishlist it if it looks interesting. Thanks!
