If we have to pick up the zombies in the beginning, why can't we pick them up when they fall out of the truck? Also, there need to be way more in there.
The first window I encountered was 3500m in. I enter it easily and land on a box. This throws me off just enough to make me flub my exit and fall to my death.
Normally I'd rate a game like this only two or three stars because the plot is twisted around a moral message (one that I agree with, but I hate all moralizing games). Then the ending song played.
This is like, the best thing I've ever read.
