Congrats on finishing Foolish Mortals, Mad. I picked the game up last week.
I've gotten stuck a couple of times in The Final Chapter but figured things out after taking a break. So far, so good. I have two unexplored places on my map right right now that I'm hoping may shed some light on a couple of puzzles, or at least not get me stuck again.
I am toying with the idea of playing Limbo of the Lost but haven't started it yet.
