Tower Defense V

The merchant came over saying, "You earned 39,150 points this round, would you like to purchase anything?" he asked.

"Can I buy more puppets?" I asked

"You can, but you'll need to upgrade your base first, there is a limit for each base on how many puppets it can hold."

I had no choice but to upgrade the base once more and obtain ten more puppets.

With that, I had enough puppets to man the cannons around the fortress. And more to finish up the trenches.

I began by making them lay down traps, spears inside holes, and all of that. As for the moat, all I had to do was ask the merchant for a frosted crystal that I can use. 

After making a tower and adjusting it so it could constantly shoot out massive pieces of ice into the moat, I had another tower constantly warming the ice, creating water that began filling up the moat rapidly.
