What intrigues me particularly about Triangle Wizard is the aesthetics. For a start, it's a Rogue-like, with randomly-generated levels and a variety of character and class types, and spells or abilities triggered by alpha key presses. It uses the mouse, though; left-click to trigger the selected spell/action, and right-click to move to the moused-over location. But it's also a realtime game, with monsters acting continuously (although via fairly predictable AI), to the point that hammering on the mouse button at critical moments is essential. Diablo-esque, in a way.
