That's not you. I only tested it as a windows executable. When I exported it for HTML5, I realized it had performance issues as a web game. By then though, it was time to submit to the jam. So it was too late to do anything about it.
Like I said, I already found it and used it. The game worked right in full screen when built as a windows executable. It doesn't work right as HTML5. So I turned it back off.
I like this game. It's like I Wanna Be The Guy but without the trolling. Biggest suggestion is to give unlimited retries. Maybe have player score be per board?
