What a polished, engaging game, and it's opensource! Thanks so much for sharing.
I had a lot of fun and this reminded me of the Emergency 911 game on Steam. Very atmospheric and I can see this become a full game in the future.
Cheers.
I don't plan on making additional content to this game. I tried to make it complete in set amount of time and I'm happy with how it turned out. Also, code is terrible, it would be easier to rewrite it from scratch than expand what's there :)
