For what it is, it's very enjoyable. One complaint of mine might be that I can't really see what they're doing on their adventures when the little messages pop up. I saw a few references in there, and I think that could have been done a little better. Perhaps slowing down the text and adding in more humorous messages as they increase in level?
Otherwise I enjoyed the game very much. The sound was cute and enjoyable. It fit well with the game. The character types were cool, but it didn't seem to matter which type was picked (as most of the time they started with almost nothing anyway). The progression started very slow, and then picked up very quickly until the end. Replayability isn't very high, but I don't believe that's the point. Artwork was good. Did no experience any bugs or glitches.
Well done. :)
