Thank you for your kind words. Regarding the zombie issue, here is what I did: I published the pre-refactoring version here: http://humane-tiger.com/9dayz/ This version does not include the in-game editor (my goal for the Img27 Jam) - but zombie battles and most other things work just fine (can be played till the end). So if you want to explore the game world including fighting zombies, I recommend playing this version.
