I'm playing on harder difficulty, and even though I have like 35 something soldiers....the hordes keep getting stronger and stronger. Not only that, but I suddenly start losing 6 squares instead of the usual 2. The game is way too hard - I can't even build builders without being overrun...I need to constantly produce soldiers. Fun game on lower difficulties, but I've wasted about 4-5 days trying to beat it on harder.
Never played Runescape that much but this seems like an odd game to have on Kongregate. Runescape has its own site, makes its own profits, etc....but then again it doesn't affect me if it's on this site so whatefer.
