I really like it. I like the realism mixed with zombie apocalypse for extra fun. There are still bugs and tile glitches, but I'm sure they will be resolved. I rated 9/10, but in the future it may be worth 10/10.
The interface could use a bit of work as well, because it is kind of tedious to do repetitive tasks at the moment. Lots of &->->Enter, &->->Enter, etc.
