For a 5$ game you will have your money's worth. If your looking for a good game, this is not the one.
Getting an A rank can get very hard at time, since you have to make the time while still getting the points. The graphics in Sneak King, are a little better then expected, but they are not very good at that. You will often see the Kings cape clip his leg. The charecter model for the king is great, but the rest of the charecters date back to PS2. The sound in this game is also very bad. There is only one song playing the whole game and every level. The song gets very anoying at time.
Other then that the sound is kinda' good. No one really talks in the game either, exept one anoying guy after you beat a level. Overall Sneak King is a fairly bad game, but is still worth the 5$. Getting the game is a good idea, there are even 200 gamer points to unlock, which is probobly the most fun you will have with this game
