Mr. Do!'s Castle for the Coleco Vision. Though not the most visually impressive home version of the addictive arcade game, Mr. Do's Castle still retains much of the original's fun on the Atari VCS. The game casts you as the cunning clown first seen in Mr. Do! (which itself was made for the Atari VCS by Coleco, though the rights to the sequel ended up with Parker Bros.).
The beauty of the Atari VCS edition is that you can tell which blocks are the walkway blocks, which ones are the key blocks, and so forth. The graphics are just detailed enough to ensure that the game is playable, which is fine - it's more important to keep the game's sometimes breakneck pace intact. You have fairly good control over your onscreen alter-ego, and even the jaunty (or irritating, depending on how you look at it) theme music is included.
An interesting trivia/collecting note: due to the production runs of some of Parker Brothers' final video game titles, Mr. Do's Castle is considered a rarity on almost any system. These days, obtaining a Mr. Do's Castle cartridge -- especially with the original box and documentation - will likely cost you more than it would have when the game first came out.
