This is one of the worst games I've ever played on Kongregate, it's one thing to have a different experience each playthrough, it's a whole other thing to have every enemy be a boss and then every enemy be a drone back to back on the same level.
For some reason the game keeps running fine for awhile and then starts getting massive multi-second unplayable lag spikes until it starts to freeze the whole computer. Flash has to reset to stop it.
The first two badges only registered for me against the Reckless (easy) CPU. I tried both pvp and medium beforehand, nada. Thumbs up to help BOTD hunters
For anyone who is trying to get the BF badge, all you have to do is keep going in one direction away from the start, the further out you get the harder and more frequent the bosses are. I recommend waiting until you're in invincible mode.
