About Mono
Mono is a 2D action game set in a monochrome world. You play as a protagonist who arrives to resolve a crisis, travelling with an AI companion and challenging the bosses in each region. Defeating bosses and gaining new abilities expands the areas you can explore.
Boss battles
You read enemy movements and switch between the protagonist’s melee attacks and your companion’s ranged attacks. Hitting a boss while it performs a specific action triggers a Critical Hit that deals massive damage. Your companion’s ranged attacks can also put enemies into a Break State, making them take more damage and creating openings for you to attack.
Exploration and upgrades
Enemies grow tougher as you progress into new areas. You gather materials by defeating foes and finding hidden items scattered across the map, then use them to enhance your abilities. Upgrades can increase HP and Attack power, and can also unlock new actions.
