This is random, but on the loading screen in the top left corner it says, "For 1 Or More Adults Ages 10+". Sooooo... 10 year olds are now adults? Explains why Ash Ketchum's mom lets him go wandering around Kanto on his own. :)
To be honest, I don't even think this deserves to be a Badge Of The Day. Its just so... boring. Average rating 3.8? That is waaaaay too high a rating for this game. There's not even any music, and the hard badge really is hard, for only on reason: by the time you get to wave 30, you probably would've fallen asleep, and it won't be worth it anymore, 'cos the truth is, it's just not fun. For anyone who has just got onto this game, and is looking at the comments to see how good this game really is, take it from me, its RUBBISH. + THIS COMMENT SO THAT OTHERS WON'T WASTE THEIR TIME PLAYING THIS GAME.
