Thanks. Re: controls did you try the fullscreen button?
I did! But I also have several screens, so might have been that. It wasn't a huge issue, it was definitely playable anyway and I really enjoyed it :)
Ah, I did most of my testing with the built version but couldn't be bothered to get all the exports working in time. HTML5 is pretty good for most things, but mouse control in FPS style controllers are still a pain
