What the heck? – Galactic Fortress Defense Review

I played the one map, beat it, it put a key on it. So i click the next map and it comes up and says "Do you want to unlock this map?", I click YES (thinking it uses the key!) and it asks to confirm purchase??!? So, you have to pay to even play a second map?? Thats lame! Also, the sound effects are annoying and some are too loud.
