Video games: 'Stacking' attack

With releases such as "Brütal Legend" and "Costume Quest," Double Fine has cemented its reputation as a go-to developer for unique gaming experiences, even if the company's offerings don't always find an audience. "Stacking" may be Double Fine's most niche concept to date, but it's hard to imagine a player who wouldn't enjoy the game's clever puzzles and charming story.

You play as Charlie Blackmore, the innermost doll and youngest child of the Blackmore family, a Russian matryoshka set. After his siblings are kidnapped and forced into child labor by the evil Baron, it's up to Charlie to track them down and free them. Luckily, Charlie has the ability to hop inside larger dolls, each of which has a special ability. Some of these abilities are purely for entertainment, but many are vital to progressing through each level.

Despite this novel mechanic, the core gameplay of "Stacking" is the same as any good adventure game: creatively solving unique and humorous puzzles. Each level contains several challenges Charlie must overcome, which in turn have several unique solutions. Upon completion, a puzzle will instantly reset, allowing you to try it again without having to reload a save. This ingenious mechanic solves one of the most common problems with the genre: searching for an off-the-wall solution that only makes sense to the developer. An optional time-based hint system reduces the puzzle-based frustration to nearly nonexistent levels.

The Baron's evil traps aren't the only problems you have to overcome. Your character is about as responsive as you would expect a wooden doll to be, and his sluggish pace is annoying. The sense of progression also falters; while you unlock the ability to stack with larger dolls as you continue, it doesn't add much to the gameplay. The biggest changeup is the ability to combine characters' powers. This leads to some great puzzles, but this mechanic shows up too late in the game and isn't used enough. "Stacking" ends on a high note, but the rest of the game could have used more gameplay twists like those introduced in the final scenes.

Despite only the most primitive of animations (most dolls can only move at their midsection) the characters are memorable, and the Blackmore family is positively endearing. Humor plays an equally important role, and "Stacking" delivers. Most of the laughs are pretty adolescent, with no shortage of dolls that feature farting as their special ability. If you're too stuffy for this breed of humor, you can expect more sophisticated laughs, as well.

"Stacking" is a bit rough around the edges, but the puzzles are clever, the humor hits the mark more than it misses, and the characters and story are delightful, leaving adventure fans with little more to ask for.
