Simpsons and shoot em up, pretty interesting combination! The 3D environment works well, with the overally simplistic style for characters/sceneries, and full 3D for certain items (like the donuts). There are a couple of features I'm really missing though: ability to strafe to better navigate around corners without exposing yourself to fire all the time, and ability to use R to reload. Free aim with mouse would add a lot to the game as well, if possible. But either way just the 3D aspect of the game is pretty impressive, good sound, good story, good stuff!
