Rogue Dungeon RPG

This is a portrait-mode, solo roguelike dungeon crawler with a simple art style that runs smoothly on most devices. Players can jump in for short, intense sessions, with progress saved automatically, making it highly interruptible and suitable for quick bursts of play. Monetization is fair, with optional IAPs that don't block progression, and the game offers high replayability through randomized runs and permanent bonuses earned after death.
