cool but dissapointing
The menu system is awesome, and the transitions between the decision selections are great. You should put some focus into the menu, but not to the extent that you run into problems with the gameplay itself. It's just not fun. I guess you get +originality points for at least changing the "Defend your Castle" genre ever so slightly, but it still plays like every single other game like this I have ever played. You could have mixed up the gameplay up so many different ways, but no. It's the same stationary camera looking at a nonchanging background where nearly identical enemies come at you from one direction, and you click on them as fast as you can from a different direction.
An awesome menu system is great but it can't trick me into thinking that I'm having fun.
