I am not always sure about the games that I get, because I’m not sure how fun, or good they are going to be. I have downloaded a bunch of games that were fun for a little bit, and then aren’t fun anymore. But this is really challenging and fun! It really is addicting, and the only problem is that there are not enough levels. If there were more levels, it would challenge people to want to complete a bunch and it would keep people playing instead of just finishing all the levels and just quitting the entire game. You could maybe just add new levels every month or so, if you have that amount of time, I guess. But it would be fun to have new levels every so often. That’s it. Other than that, this is a very challenging and addicting game!
