I do enjoy the psychadelic feel the game has to it. The graphics and audio really play into that, you could try distorting the music with more and more smoking to give it a creepier feel. Though the game doesn't have much in the way gameplay wise, I understand the purpose was more to show the dangers of smoking, though you could have made a few little obstacles in the way to spice it up a little. It's a unique realisation of the theme though, but it wasn't what I was expecting. Good job.
