An excellent short, with an engaging story and puzzles that were just the right level of difficulty to keep the gameplay fluid.

One note: I did have a problem entering the code from Level 2 for some reason - I ended up having to type the code, press enter on my numpad which highlighted the code, and then had to hit enter on my keyboard to actually submit the code. Not sure if I missed this instruction in the game, but I didn't remember having to do that on Level 1. It made me nearly stop playing at Level 2 as I was sure I had the code right, but couldn't understand why it wouldn't accept it.

Apart from that, a great experience.
