I've been using this mod for several months now, and I just love it. I am highly considering donating once I get a job (I'm 15, lol). But anyways, time for the compliments and complaints.
Firstly, I love the way how you have made up the ships. It's much more attractive looking for and diving to wrecks than spending countless hours in caves searching for boring dungeons. The air pockets in some shipwrecks is pretty nifty too.
However, certain, almost entirely technical and coded aspects of this mod let me down abit. A major problem I've noticed is ship spawn rate. In 3 hours on survival all I found was a single sloop after 4 kilometres (3~3.5 miles) in a boat.
Besides this, only one more problem: You're stealing peoples jobs man, you're too good at this! No seriously, you're hurting their self esteem. So don't be a jerk...unless that's your nature:P
