Well, I just received my copy in the mail today. Haven't played it long enough to write a review yet, but, so far- awesome.
The opening screen has an image that easily rivals the similar screens in the NES' Star Wars.
Then, an attractive title screen.
Then, a good demonstration screen.
Then, the option screen. Included is a "bomb" option; by clicking on a jewel with a blue bomb on it, you destroy that one jewel. This is not an option I've seen in the on-line versions.
There's a high score screen(s). You can enter your initials (3).
The graphics are great, better than the screenshot would indicate. Sound is good, too.
Control is a bit tricky at first, but you quickly get used to it. The Roller Controller can be used, too.
Finally, this is the first "recent" game to have appeared on the ColecoVision in a long time. It was well worth the $30.00.
