I have never played a game in this genre (if another exists) but I can definitely see the appeal in it if only I had more time to give it. Even though I ended up trying and failing 5 times (two of those times the ranger and wizard refused to leave the starting room even though the knight and thief had ventured out already and no enemies were close by to prevent them from joining the other two) I still found myself wanting to try 'just one more time'. Surprisingly I wasn't annoyed by the music at all (in fact I would say it complimented the game very well and kept everything buoyant and approachable. Had it been more serious music I probably would have given up after a second try out of frustration from not being able to completely understand the game).
It would be pretty nice if you continued to work on it just to see where it ends up!
