Hello!
Thank you very much for your really fast answer. Regarding the save, What if I don't want to complete the game in one sitting? I wonder why other players didn't mind.
And the instructions on the screen say: place with 'F' , throw with 'G'. All you have to do is replace “F” with “E” and the problem will be solved…
Regarding the framerate, I've found a solution on my own: I limited the framerate through the graphics-driver.
The game is very interesting indeed. Hope there will come more...
