Heya!

I am so excited to play this game but when I launched the application it only shows a beige screen with the words NW.JS on it...Could you please tell me how I can get to the actual game screen? 

All the best!

Hi, did you keep all the files in the same folder they came in? That could happen if they are separated.
The Steam version usually runs with no problem on Mac, so if problems persist, you can claim a key and activate it there.
