Nice game. I like it.
Please add a button to toggle double speed on and off. Holding down the mouse button all the time incredibly needles. Also u should allow more and better upgrades. Who needs better refunds from selling towers? We need bigger guns! 3/5
1. It would be very useful if the hitpoints of every level of the castle would be displayed. 2. The that says that I can't do something right now is very annoying. Otherwise good and fun game 4/5
