Has anybody figured out what the buttons do? I feel like I'm close...

I installed and started the game. I'm moving to the gate, click on it and the game freezes. Going through the tasks in Windows and selecting the game again results in being able to control the game with the keyboard again, but the mouse doesn't react. On top of it, there is always the windows task bar displayed, I can't get it to work in full screen. Using Win 10 and keyboard/mouse controls. What's wrong here?...

Hey, how does it work, please? Are there chapters and progress will be saved at the end? Or are we supposed to get it all done in one sitting? Thx!

Ive been playing this game for hours trying to figure it out.... I know several things end the game, and Ive got to be missing something. when you get to the water area place theres some sort of cryptogram? am I missing something with that, because after all the letters flash on screen and the talking stops I cant figure out anything else to do other than walk off the edge and end the game....

How many hours of gameplay are involved. Game looks pretty awesome
