A nice homage to half-life/portal. A lot of implosion in the voice audio and different volumes which made it a bit jarring. Otherwise the actual lines were definitely great in terms of pacing and how the character sounded. 

Wish there were more audio lines because the level transition are very long and I didn't realize until now because portal always had the witty dialogue to break up the monotony of waiting. The floating blue boxes is a cool idea. Aside from seeing what half-life mode does to your model I'm not sure if it actually changed the gameplay in anyway since I didn't replay the game a second time.
