Not Challenging at ALL But great game.
As many have posted previously this game in actuality lacks a certain degree of difficulty,perhaps if your in the 6yr old to 12 year old range sure this could be difficult as ones hand eye coordination has not fully developed yet and perhaps the linear thought processes needed beyond that of a button mash-up game.I would make the suggestion that you beef up the time limits for the user and allow them to change it around.All in all a decent game however the animation style does reminesce of an adult swim game,meh I dunno keep up the good work though and perhaps work on the incessant lag the game picks up on in later levels.Good luck mate and Cheers
