Bonanza Bros.

One or two bank robbers move up and down floors collecting treasures and avoiding the cops.

Each level is a building such as a bank, in which one or two robbers try to steal all the loot and get to the roof to be taken to the next of 16 levels!!! its horizontal side scrolling with the ability to move up (away from player) to avoid bad guys (cops) and stuff... seems peculiar, very fun to play!!!
