That's an impressive time IF you didn't look at YouTube, social media, forums or WIKI's... I personally took it easy, tried all sorts of things, built my bases before killing the first boss... This game appeals to many different types of players.

I actually found it more satisfying when I killed the second boss in the swamps. But if you have a bit of an impatient personality, I can see it might not be so much fun. One suggestion: if things aren't going so well in the swamps, don't be stubborn, just consider different approaches, and nothing wrong with taking your time as well...
