Ran across this library addon and figured this is a good place to throw it up. Could involve things like placing a Periodic tower, getting over a certain number of points in Wave 61, winning a Race game in less than XX minutes, etc.

"God of Element TD" - Beat Extreme, VH, All Random, Chaos, Normal Length.

... still need to do that myself...

Though technically it's hardest from Very Short.

An achievement system to the game would be great and would encourage people trying out crazy things just to pull something off. For a Tower Defense game, it's great for learning.


"Money Hog" - Get a networth of 1400 gold by the start of round 16 (my single-player runs have me end up between 1450 and 1550 gold).

Just some random ideas.
