You are right that fixed it. For anyone else playing, switching from Vivaldi to Chrome fixed it, which is a very strange bug. Anyway, it's a really nice concept and good platforming. I enjoyed it. My only feedback would be that the losing sound gets a bit repetitive, but other than that, great work! The futuristic environment is very cool as well; I actually wanted to have a similar background of buildings in my own game, but I didn't find the time to add it in. Good entry!
