Demonic Mahjong fuses mahjong tile-matching mechanics with a roguelike structure. Players must use tiles from their hand to create combinations that follow set scoring rules. However, the main goal goes beyond simply accumulating points. The ultimate goal is to build a hand and strategy to defeat the main boss, making each run a preparation for the final battle.

Desperate Place picks up after an incident on board a colony vessel in the year 3040, en route to the planet KOI 7711.01. A sudden wave of ion radiation from a red giant planet damages the starship’s helium-3 fuel tanks, forcing an emergency landing on an unknown world. As a crew member who wakes up prematurely, the player is faced with the need to mine resources, repair vehicles, and survive in the face of local threats.
