The thing that makes it worse is (as you can read in the comments), that the game was pretty much advertised all around as having 3 chapters, which makes it look like the 3rd chapter was just cut out of the game. I hadn't actually realized that, until the writer of that review enlightened me.
First time I've heard of this! Maybe the reviewer was smoking something. :P
Tiller's been pretty open about there being at least one sequel which would continue the story. I hope it's released soon.
