Unfortunately, the game was unplayable because the fps was really low (looked like 5-10 FPS), even on the lowest settings and resolution on my 2 year old top-end mac. It's not very obvious you have to click on the text at the beginning and the selection indicator is a bit subtle, in my opinion. Also, some of the text descriptions were overlapping and were unreadable.
Looks interesting though. I was able to walk around the island for a moment before I got frustrated with the FPS.
