Dungeonism is a turn-and-tile-based dungeon crawler. It’s not quite a roguelike, but it is rogue-ish.
Taking equal inspiration from Pac-Man and Temple of Apshai, Dungeonism combines the strategies of turn-based RPGs and tile-based arcade games into a single unique gameplay style. It is engrossing enough to be played for hours, but its turn-based rhythm makes it easy to play in short bursts.
