One of the best arcade roguelikes (or roguelikes, if you're a purist) out there. Difficult to beat completely and oh so very satisfying. Gazillions of unlocks, secrets, bosses, power-ups and item combinations. Limited co-op (BoIR only). The game can be genuinely terrifying and dark, especially if you take a moment to ponder what's really going on with its backstory and characters.

With an arcade style feel and fairly quick play through the game makes it easy to sit down and play for hours.
