A great PSP time waster
I'm not sure how many people use their portable devices in this fashion, but I am the type of person who picks up a psp for 20minutes before bed or while on a bus. Half-Minute Hero is the perfect game for that type of situation. Each level is self contained and takes a maximum of 5minutes to complete. That's not to say that they are all simple. As the game progresses the levels get more complex, and the two optional missions are less obvious.
The art style is cute, and the dialog pokes fun at classic RPG cliches. I recommend this to anyone who is looking for a light and fluffy game to kill time with on their PSP. People seeking deep game play might be a bit disappointed.
