Remember
this? That MLP:FiM tower defense game? Yeah, well,
here is the sequel.
Here's my way for getting past Nightmare Moon, at least on the first spiral looking map. First, put a
Lyra just below the first turn (coming down from the top) and a bit to the left. Boost her attack and speed to 4 each. Then put a second Lyra in that little groove just at the final turn going into Canterlot. Again, boost her attack and speed to 4 each. Then put a
Dr. Whooves between the two Lyras and boost his range to 5. Then go back to the Lyras and get their attack and speed up to 5. Lastly, try to get the range on the two Lyras as high as you can (I can usually get them to 3 each). That should be enough to beat Nightmare Moon at wave 10.
After that, though, you're on your own. Finish upgrading the ponies you have out there, then start putting some of the others. I was able to get up to around wave 42 or so before losing, so far. Don't neglect the ponies' super abilities (e.g.
Octavia's constant stream or
Bon Bon's explosive attack) or the support ponies (
Zecora,
Wild Fire, etc.) or the super abilities from the Princesses. Each have their own tab at the bottom.
