I was bored last night, I happened to run across this XKCD earlier in the day, and I needed a study break, so (half in the bag) I grabbed it off Steam or Stream or whateverthefuckits called.
Kind of a fun game. I got through about the first 15 challenges in a little over an hour, and the gameplay is pretty entertaining. I just need to get a little better with that gun.
I hope you played it with the sound on. The computer's dialogue is some of the best writing in a game I've heard in a while.
