Thank you for your swift response! It seems like I am in bad luck with getting the game to function properly on my setup. I downloaded and installed all the necessary packages and was able to start the game, yet I sometimes cannot open the start menu and was unable to save the game yet. Also, when I got digested for the first time, the screen just turned black, I could still hear music but I couldn't retry the level or anything. Edit: Resolved, I'm sorry that I was too dumb to read the other comments, the solution was explained there ^^"
