Issue. As terrorist: Tried to place a tower first on level 5, will not let me place tower, cancel purchase or access menu. (IE: can't do anything while enemy eats me alive.)
So much for my morning. Went to try it a little, played it a lot! Great job.
It did crash on me though. Same issue as stated above. All three power ups and a great deal of green stuff.
A good game with a lot of potential. I like Youngbulls1983's suggestion of multiple enemies to outsmart. Perhaps changing the shape of the board rather than the available playing field. As I said, great potential.
