Would like a speed up button, btw cool use of limitation :D

I think the biggest issue is just speed. The balance is good but everything just happens too slow. Once your towers are placed you just sit and wait for a while.

I liked the game music and visuals. I wish we were able to see the tower radius before placement. In the last level I put two towers in what seemed to be the middle of two roads one of them couldnt hit either roads and the other only hit one side. That was a slow death xD
