This game is a classic-style puzzle adventure strung together into a thin plot. Your keys are stolen in a cheesy Christmas area at a mall, and you have to get it back by operating a series of complicated machines.
This game hits up a lot of the classic puzzle types. Light source puzzle, complicated lock and key, disassembling and reassembling items, removing obstructing NPCs, trial and error puzzles, etc.
The puzzles are mildly difficult for a puzzlefest and the game is not too long. A compass rose aids navigation and the writing spruces up the whole affair.
Basically, if you like Not Just an Ordinary Ballerina, you'll like this, it's younger, smaller cousin.
