Well, we got some good feedback from the private demo. I've been pretty busy cleaning up things and making a number of changes to make the current demo better. For instance, I've added Alt+Enter functionality so that you can change whether you're using fullscreen or windowed mode at any time. I've fixed a few bugs associated with clicking a different window when you were playing, and I've added an option to take screenshots by pressing the PrtSc button. I've got those being saved in your documents folder along with the save files. I think those are the major changes that I've done, but there are a few more incoming before we make the alpha demo public. Hoping to get it out there in the next few days.
Thank you for your patience!
