Que Bit is one of the closer clones for the Coco 1/2 of the arcade hit Q*Bert. It even features an attract mode. I don't know if this game had a wide distribution... I don't remember seeing an ad for it in any of my Coco magazines. It was Received and Certified in April 1985's Rainbow... although it falsely labels it as being able to run in 16K RAM.
The version available for download here (and the intro screenshot) have been updated with the proper, unhacked ones. This fixes some title screen glitches, and also plays the game at a much faster pace, closer to the original arcade speed.
