Hey thank you, I put this as a reply to your other comment but in case you missed it:
If you signed up to be a playtester, you should have gotten your key for the new levels already (search for "Lo-Fi Room" in your inbox). If you haven't signed up yet, you can do that: here and you'll be able to try a version with 12 levels total. I'm going to send those keys out at the end of this week, so if you haven't already, make sure you sign up before then~
