So my friends computer is doing the same thing with a different game, so I think that it's our computer not itch.io.
Unfortunately is sounds like it is blocking iFrame content, which is how a lot of web games are run :(
That does suck, is there anyway to get around this or do I just accept the fact I can't use itch.io anymore.
I'm not too sure tbh. Maybe contact Itch and see if there is anything they recommend doing.
Sounds good. Thanks anyway though.
