Shiren is a roguelike that is a mix of hard-core dungeon crawling and cryptic Buddhist mythology. It has an extremely punishing day-night system that fundamentally changes the gameplay loop each time it cycles. It is a fantastic game that encourages the player to problem solve rather than engage in repetitive brute forcing. It stands out as one of the best games in a genre full of mostly derivative and unimaginative content- procedural generation is not a crutch, but instead a sandbox within which you demonstrate your mastery of the ingame mechanics.
