So I'm playing for a few hours now and loving it (I'm on the second island now). I watched a few YouTube videos to get a general idea and what I was wondering is: how hard is this game (playing on easy, that is). The tips I'm hearing in guides all say "be fast, don't waste time, enemies get stronger" etc. So are they gonna scale infinitively and get too strong at some time? Can I maneuver myself into a dead end by having too few defenses and lose all my island and have to start from the beginning after 20 hours? How likely is that?

I want to take that game slowly and explore by myself but I'm afraid I will lose and I don't want to start over..

Thank you!
