If a player has finished a certain level, maybe it could be good to continue the next level by not starting all over again from the 1st level. I hope that you could change something like stopping at a checkpoint so that players could not repeat the same route again, it kinda bores when it does. I mean it's a really good game, my siblings and I used to play this on Samsung galaxy Young before, it's good and entertaining but like I said, going back all over again kinda sucks.
