Potential?
Could use some real improvement. The defensive drones rotation speeds were seriously to slow.. and their AI was idiotic, rotating 290 degrees right (if pointing up) to shoot a target just a hair to the left, and income was way to harsh as well. Some creatures attack power was way to high considering their other stats (the blue rush zombie in day 8 i think of the Foot Ball defence. If you try to create a GD 2 try to improve on these features. Also while shooting i would try to move and the aiming was a bit glitchy, forcing me to take damage while having to stop moving and shooting until it righted itself.
