Looks and sounds fun as far as I could get... Unfortunately the game turns all grey except for the mouse pointer on my G14 in the middle of the conversation with the fisher man at the beginning.
Hey, thanks for letting me know. This has happened for someone else, but I haven't been able to reproduce it myself. It's something to do with local display settings.
Could you try the steps described here and let me know if that works?
I'd also be curious to know your monitor resolution size and display scaling %.
