Taro Ito-san of GameDesign just released a new game, though it is a bit less accessible than his previous efforts. Escape from the Starship is an escape game that uses sound to convey the relative proximity of monsters that you must avoid.
The starship is composed of a maze of rooms, each of which is composed of homogeneous grey dots. Each dot represents a floor tile on which you may land. The sound you hear, however, ultimately determines whether that tile is safe. As you approach a monster, the consistent "beep—beep—beep" will increase in frequency. Your job is to find safe passage through the spaceship without landing on a tile with a monster. Find batteries to replenish some energy for your beeper, and find a map to help you discern the twisty passages of the starship.
As usual, Ito-san creates an engaging puzzle game from a simple concept, and it's enjoyable to play. Since it requires sound, however, this game is best played by hearing folks only—an accessibility "don't" that may have been averted by including an option to display a similarly pulsing object or symbol synchronized to the sound—and those in an environment where the beeping won't be disturbing to others.
