in some levels, the hero icon is blocking the numbers of enemies incoming >_> (like the artifact level with the mages). Also, like others have said, no money for skeletons part of the wave? >_< The gatling tower originally makes it a 5/5. but i wants money from skeletons from waves. 4/5
After trying like 500 tims on Level 59, I beat this game. This game is hard. and dude, where's the save point on level 59? Half the frustration comes from having to replay the beginning and botch them again and again. And then the few times I get over to the magnet before the giant moving square, I usually botch. Also, where you get those soundtracks? If you're doing a sequel, the last few levels please have more save points. They're like mini accomplishments ._.
the game is terrible at reading if the ball missed or not. and sometimes when the game gives u extra balls, the one you shot isnt counted to pop bubbles. blah.
I beat the game! Yay~ I was hoping there would be art of each gems back in their town for some reason... (there's like not a lot of goldenbrick resort? XD)
