Backpack Dungeon is an indie strategy RPG centered on an innovative inventory management system, where item placement is as important as the items themselves. The core gameplay mechanics transform your backpack into a tactical puzzle, where item effects are triggered based on their orientation, proximity to other items, and placement on the game grid. Players must carefully arrange gear of varying shapes and sizes to create optimal chain reactions and synergies, balancing active effects and passive bonuses in a confined space.
