Alper pointed me to this slightly retarded but at the same time engrossing reinterpretation of the computer RPG: missions and enemies are laid out on a grid. You finish or defeat them by clicking repeatedly (shades of Cow Clicker here). Then hover over the XP and money that appears to cash in. To get to the harder ones you need to level up and purchase kit. There is no declarative layer what so ever but it still works. Strange.
