Ok, I updated to love 0.9.2 and the game ran just fine.
It was a very nice game and quite a bit of fun. It feels quite polished for a game jam game. A few thinks I noticed while playing.
It took me a minute to tell the difference between walls and unseen areas. Perhaps some visual distinction would be useful?
While running into dead ends with a horde of zomboids behind you can be exciting it also seems like getting far is a matter of lucky navigation. Perhaps some way of hinting towards the right direction would be a good mechanic. Footprints? Bloodstains?
