When I start the game I get an immediate exception as seen on attached screenshot. Can anyone help me with that?

Ditto, I get the same thing. :-/
Okay, talked with Ethan that works on the game, it seems the game bugs out when you have the TERM environment variable set to anything but "xterm".

Run the game like this: TERM=xterm ./start

That should fix the issue, works for me.
Works for me as well, thanks!

Still, this is a severe yet simple bug that should definitely be fixed.
