I don't see why people whine about lag. Played it at high quality, "amazing" settings, and never experienced one slowdown. Built my PC on $350 and actual computer knowledge. Sad for you if your $800 Best Buy PC can't handle a simple flash game.
Absolutely hate the assassins - the 50% chance to dodge is a load of crap because it's basically down to luck if they die before they get to your gems. You could have at least made the meteor impossible to dodge so we could kill them without having to spam the 2x ROF spell and pray they all die. Other than that this game is awesome.
