About Concurrency
Concurrency is a roguelike set in randomly generated halls that loop back to a shop. You follow a track, fight procedurally generated goopmen and buy upgrades from the shopkeeper. The game presents the halls as having no secrets, hidden levels, genres or bosses, while hinting that there may be more to uncover.
Paths and upgrades
You choose your difficulty by taking branching paths, and the shop offers plenty of upgrades. The levels are generated so that you do not encounter the same one twice.
Hidden content
The game contains an adventure described as hidden just below the surface, lasting about 2 hours. It also has 8 distinct genres to uncover and master, along with dozens of hand-crafted levels to unlock.
