There is a slight bug where if you fall into a net surrounded by foundations you are unable to get back out of it by jumping or even trying to swim under it, then the shark gets you and BAM you die with no way to escape. Also there is an issue where you cannot place walls around the staircase. You must first build your walls then place the staircase afterwards.
If you would like a full time tester please send me a private message i am also good at finding exploits and certain other things that could potentially be game breaking bugs Etc.
