Let's dive into this dungeon. No reason, other than it being great fun! But first, a bit of history.
Actually, there used to be a mobile version of Brogue at some point in the past. Though clearly, porting a game intended to be played on a large, landscape oriented screen using a full physical keyboard to a small, portrait oriented device with typically only a touchscreen can easily be considered a Herculean task. Interface clunkiness being just the tip of the iceberg of major obstacles.
