it seems to be a problem tied to your environment specifically, as it works for everyone else. It's the first time i'm hearing about it, and i can't fix bugs i don't know exist. Next time use constructive feedback to help me fix issues together. I see you use firefox, i will check if there is a problem with it..
also, pocket platformer wasn't changed in over 2 weeks, as i was on vacation. so the problem must be on your side
