Really quite well done for a 2-day challenge. I love the concept. Lots of the other suggestions here are great but I'd just be curious to see what you do with this concept and some more time. I beat it and want more :)
one of the levels is literally impossible. The help doesn't tell you anything about the different types of towers. and with no upgrades this game is whack. 1/5
A potentially really really fun game. THe fact that I have to keep graduating my team makes me depressed though. I don't like the fame requirements. They happen too quickly :P 4/5
I agree with the preivous comments mainly. More levels or some time of Survival mode. And definitely an upgrade chance to a money magnet. 5/5 though. Awesomely fun!
There are a lot of errors that happen, at least for me. Like I get to a city or a battle and can't do anything. A lot of glithces that require you to reload completely...
