You should be able to play in-browser, but you can download too. If you can test either as a tester let me know. It'd be neat to test both.

Use the walkthrough or not if you want to. The map is more for reference, as there aren't too many rooms yet, and I'm not planning for them to be. But it'd be nice if you can check to make sure there are no mistakes. I like to provide ways to test if you aren't feeling up to much, because trust me, it's useful.
