.zip the folder with your game files, not the game files themselves. The "highlights in the menu" are near invisible when you hover on a button. "Privacy Options" takes me to the browser to opt out of Unity, doesn't leave a good first impression. Loading freezes screen for 10 seconds. Pressing escape to go into the menu keeps the mouse locked in Windowed and music blasting, neither are good player experience. Music still plays even on minimization. You're saving files to my PC/Pictures, why? just put it in the folder where the game is run from. Everything is very frustrating due to the bad camera controls, which is something out of a strategy game but mixed onto middle mouse button, no sense of what you're doing and not being able to do what you want because of all of the grating nonsense you have to put up with.
FATAL BUG: start game, press escape, wait some seconds, press escape, get launched into infinity. Happens every damn time I pause to write something here. After around 10 times, I had enough.
Alpha version isn't an excuse for any of the above.
