The Night Cage - Board game

The Night Cage is a fully co-operative, horror-themed tile-placement game that traps 1-5 lost souls within an unnatural labyrinth of eternal darkness. To win, players must each collect a key, find a gate, and escape as a group. Escape won't be easy as each player's visibility is limited by the weak light of their candle. They illuminate only tiles directly connected to their own, and when players move, tiles that fall into darkness are removed from the game. Doubling back the way you came only opens new paths, the old ones being lost forever with critical keys and gates vanishing if your light move away from them...
