Perhaps I can gather some information from you? What browser are you on? have you tried the GD.Games version? Are you mashing the skip button maybe too fast?
Me, the rest of FENRIR, and our teacher as well all attempted to run it both on gd games and itch, the issue is after the light, i tried different methods to no success, if maybe you wanna send me a personal copy i can run up on discord i really did wanna play it!
