It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

We have an experimental branch in GoG that you can opt into. That is where you can try the latest cool features we are developing, but it is also slower since it has more debug features, might break saves etc.
This has not passed through QA, so opt into this at your own risk!
