I wasn't able to implement the new voice acting because there were still some important bugs that needed squashing, mainly script bugs that I saw in Youtube videos. I also put in a couple more clues to make Chapter 4 easier, added a few more coins under the ocean, and improved some textures. Most importantly, I fixed a bug that crashed the game when quicksaving with F3 in the World Editor, and I also fixed a bug that prevented you from giving stacked items to teammates when you talk to them.
Version 3.2 will be out before the end of the month. It will have new voice acting and probably a couple more bug fixes. Then I'm gonna take a break for a while.
EDIT: You now get a skill point every time you catch a fish with your bare hands (up to 5 times).
