This game is by far one of the best defense games I've ever played. AWESOME JOB! I can't stop playing it.
The only thing I think could use some help is this. More balance with the missions. Their too short alot of the time, depends on the map. I'd win before I unlocked all the buildings. Make it easier to build walls, making easier to biuld them faster, and in return for that add more enemies over time.
