Adventure Inlay takes great inspiration from the classic Milton Bradley board game Perfection, where you have to fit a bunch of polygonal pegs into a board before time runs out and everything explodes. But, while Perfection was about as nerve-racking as a board game can be, Adventure Inlay slows the tempo of the action down to a crawl, allowing you to take on the shape-based puzzles at a much more leisurely pace. This makes it much less prone than Perfection to give you the shakes, but it also cuts down on much of the inherent challenge of the game.
For most of the modes, you're allowed a fair amount of slop--pieces scroll across the bottom and those you deem unusable can be trashed to make room for another. But in the game's most challenging mode (and, interestingly, its slowest-paced mode), you're given a specific set of pieces that you have to fit into the board. The game's methodical gait is complemented by mild jungle backgrounds, game pieces that look like polished mineral deposits, and some narcotically mellow New Age background music.
