Hey there, I know this is WIP, but I thought I'll mention it in case it's a bug. In Chapter 3 when You agree to Milo escorting you back. There are two dialogue options on a way, and neither of them has any continuation making game stuck.  

Edit: Never mind! I suppose it's related to the fact that I used saves from previous versions of the game. When I reached end of chapter 3 the same thing happened and I could not continue to Chapter 4, but on the "New Game" I could continue all the way to chapter 4. Is that going to be a constant until the final release of the game? If you want to continue to next chapter, you have to restart from the beginning? Would be really nice to know, thank you!
