beat normal with 6,423,827 points. My army was almost all stick men, some boss towers(1 fully upgraded), shock floors where I could(end) and inverted lightning rods put next to the shock floors. 3 teleporters too
All fully upgraded.
Takes too long for the later levels, but it was alright.
I suggest maxing out the riders and using them the most. They are the best for EXP(less mana per 1 exp point, less time per spawn, etc...), and are really great.
A nice way to earn 20 points
