Your website could use a tweak or two. I would change some of the text to reflect the fact that adrift is just a demo online and the iOS version is much longer.

+ the website javascript to load the next level or refresh the current level doesn't work on my computer(aurora firefox on osx)

+ the video doesn't work that well. (volume controls don't work, the play button doesn't work, got the video to play by clicking the video background)

overall it looks like a fun game but I am curious how you are going to make some money with this if it's free.
