Update 0.66 is out for the closed alpha, including a brand new main menu!
From the main menu, you can now choose to create your own Sandbox (with limited options as of now; mainly Resort name and the Size); Load a previously saved game (and you can have multiple saves!); and tweak a couple of basic Options (for now, panning and rotating speeds of the camera. If you have some requests, send a comment or message!)
Not only that, in game now you also have a menu you can access to save the game, change options, load another game etc:
So there you go! More freedom to play the game your way, and getting closer to Early Access features!
Oh, and there may be a pretty big announcement for the end of this month! So stay tuned!
