Izuna 2: The Unemployed Ninja Returns

Aside from the lame weeb shit story, this game is pretty shallow. There is no resource management at all; the game is extremely generous about giving you items and you can heal yourself by just walking around, making it pretty damn easy to cheese out enemy encounters. Combat itself is mostly just ramming into the enemy until they die and maybe running away to kite them if your health is low, especially on boss fights. This is literally the whole game. Enthralling, I know.
