Welcome to Algodoo. Though just a note, on the second half of the course, the spinners on the right are spinning the wrong way and you should keep all of the marble in the track at the start
I dont know who did it, But I think someone tampered with the start button of the game system so when Viscoui pressed it, it shocked him and creating a short circuit which explains the blackout. It causing him to fall backward hitting his head on the corner of the arcade machine and cracking his skull. I believe it may have been Royal who killed him explaining why his hat is in the arcade. He may have gone into the computer lab to grab the toolcase and frame me. he smeared some of Viscoui's blood on the hammer and went into the gym. Someone close to Viscoui mightve witnessed the murder and avenged him by strangling Royal. The avenger would likely be one of the people there when the body was discovered. The ultimate fashion designer may also be the culprit due to her pointing fingers
