When I was a little kid, that game was great! It was really easy... I could play it for quite a while on a quarter, unlike anything else out there.
I had always wondered about that game, because I knew I was really really good at it, but I didn't understand why. I was really excited to find it in Mame, so I could play it again. It still confounded me, though, as to why the game would be so darned easy until I saw it at the Family Funspot in New Hampshire, and saw that it's a tiny little machine made for lil' ones.
