I seem to be running into a bug unlocking the second bonus mission for the xeyed. It says to finish in under 6minutes to unlock, I've played the mission several times and beat it in as little as 3 minutes and still the level hasnt unlocked.
beat round 92 and just got bored, once you have sun gods its a walk in the park, but gets too laggy to be worth playing after round 85ish. Pretty sweet all round though.
