Hi! I can't figure out where to find your game after extracting the rar file. I have the Hopeful folder open but I don't see the game application anywhere...
Currently, and something that will hopefully be changed soon, I only have the game playable on Windows. If you're using Mac, I don't think you'll be able to run the executable. It should be called 'hopeful.exe' in the extracted folder. You might want to redownload the RAR if you are using Windows and you still don't see it.
