Yeah, the new update has some additional displays to help guide the player a little. I wanted it to be a little hard because I think these types of games are often too easy or repetitive. I hope everything's peaceful wherever you are!
Ah darn! I removed the ability to build the special rooms because the currently don't do anything, and that could be a little confusing. But I forgot to make an exception for the chamber. It's not a big problem because you can just start with "assistance" and you will get the chamber for free - just don't destroy it >~< I will fix that and upload a new version today!
