Backpack Hero tells the story of the adventures of a mouse with a backpack on his back. The heroine travels through caves, swamps, ancient dungeons and other similar places. The action takes place in a medieval fantasy world called Orderia, which is inhabited by humanoid creatures. The locations here are endless. They are generated randomly every time. The adventurer not only collects loot, but saves animals. And in between forays, she returns to her hometown and helps rebuild it. As the settlement is restored, new content is unlocked. At the same time, new buildings do not make visiting the dungeons easier. You can create various builds. For example: turning a rodent girl into an archer or sorceress.

This is a simplified roguelike with turn-based battles. The main feature of Backpack Hero is its inventory system. The entire gameplay is built around equipment management. The adventurer periodically finds spears, swords, shields, bows, arrows, crossbows, rings, potions. For an item to reveal its properties, it must be placed next to another suitable item in the bag in a special way. The game has hundreds of items of varying degrees of rarity and many ways to combine equipment. Also in this project there are 40 types of opponents. Each type of enemy has its own techniques and forces the user to memorize the behavior of his opponents. During fights with them, the user opens the backpack and manually selects which item to use.
