I suggest making a 2nd if possible where some characters are unlocked through challenges and acheivements in-game. Also being able to upgrade the characters so they have less attack recharge time or better jump heights. There should also be lvls where you can only play as some characters like fish in an underwter map of birds in a sky map and insects in a jungle map. But great job on this one although i don't really like HD mode... 5/5 =)
