Brilliant game, I had a wonderful time, thank you!
I experienced problem with the game crashing on my Linux PC running a Solus distribution.
I tried to launch it using the top-level script "./ioawn4t" but experienced a segmentation fault.
I tried to launch it using the executable "ags64" directly under the data folder but the engine returned shortly during the opening with:
in "room15.asc", line 60
Error: Error running function 'room_AfterFadeIn':
Error: Null pointer referenced
I went on github and compile AGS, stable release 3.5.1 and ran the fresh executable under the data folder and now the game is now starting and running fine. I haven't really looked further but thought you might be interested.
