Great game man
This is one hell of a game. Very creative and original, not one of the normal ones where once an an enemy gets past, they're gone. It actually has something in which your tower are gems, and they are returned to the beginning by your enemy but can be dropped an picked back up by another one.
I just love TD games in general. We really need more of these, they are too good. Keep up the great work man, i'd love to see a sequel.
