I was so pumped when this was announced. What a coup for Mattel!

From the original catalog picture (see below), this game changed quite a bit. It seems obvious that the original intent was once again geared more toward simulating the gameplay of actual D&D rather than making an action game. It was initially listed as part of the Strategy Network. Since the Intellivision had been slammed for not having arcade action games, the gameplay was changed dramatically. If you look at it just right, it seems that INTV's Tower of Doom (intended to be a D&D title) took some graphical inspiration from the original concept. The game adopted the Cloudy Mountain moniker after the release of Treasure of Tarmin. The INTV Corp. catalogs referred to it as Cloudy Mountain (image courtesy of humblejack), though none of the Mattel ones ever did.

In any case, the game play is pretty good, but firing arrows is a bit awkward, using the same system as Tron Deadly Discs. If you use two controllers, you won't have to stop to shoot arrows. It would have been nice to have multicolored sprites for the baddies, and better scaling. Still the graphics were decent - the map looked quite nice! The sound is functional, with some cool effects - but sparse. Played at the toughest speed, it's a hard game. The demons are especially difficult, I always thought.

It is postulated (here) that a ROM variation exists that fixes a problem in the title screen on the Sears Super Video Arcade. I own four "versions" of this game, and none have this fix. For the curious, the Sears problem exists because of the modified chipset used to suppress the Mattel Electronics Presents text in most of Mattel's games. This failed for this game, resulting in the bolluxed up screen shown below:

	Standard title screen. Owners of a Sears Super Video Arcade get a special treat!
	The game world map is pretty nice. As you travel and your party uses the necessary tools to navigate rivers or move through forests, the icon representing the tool appears.
	The dungeon crawl uses a nifty auto-reveal mapping feature, simulating the limited way that torchlight might reveal the dungeon. Passages remain revealed once explored, keeping the spirit of the pencile and paper game's mapping of the labyrinth.

Right Controller: Press and hold: [0], upper side action button, disc WNW (position 7)

Easter Egg: When the title screen appears, push disc or side button - you have the crown!

Hyperspace Easter Egg

Credit: Modern-day credit is typically given to Joe Zbiciak. However, one of my best friends showed this one to me back in they day, so I'm crediting Kim Lathrop.

During Game:

1. Go all the way up to the NW corner of the map
2. Go NW again
3. Keep going NW until you reappear in the center of the screen
4. Once you reappear, move again - you're then free to move normally

Easter Egg: Doing this will save you a lot of time. Of course, you might get stuck without needed equipment, too!
