Maniac is incredibly janky, to the point where the menus don't even work properly - I have to mute the music every time I turn the game on because it's just not very good and the setting never saves. Sometimes that works to Maniac's benefit, though, it's really funny seeing giant tanks and trucks flying around the map trying to negotiate the world's extremely bouncy physics. You'll have fun with Maniac if you don't take it too seriously, at least enough to make it worth its $5 asking price and then some. Mild recommendation.
