I got 92. Is that good? :D
This is a nice one! The mechanic kind of pushed the idea of a frantic zombie apocalypse experience where you aren't an action hero, so you have to stop and fumble with your gun in order to shoot at the zombie chasing you. A nice exaple of a mechanic conveying a feeling.
Also I liked the humor at the start - the only thing was interacting with a text interface while still having control over the character took a second to understand.
Still though, a really solid entry, well done! :)
