Okay, I created an account just to comment on this, because I played it through the HQ Residential House Game Jam and thought it was awesome! I got stuck at one point for about fifteen minutes because I knew what I had to do but couldn't figure out the command to do it, and wandered around the house wondering if I'd missed something, but, honestly, that was my only issue.
There was something really spooky about going into the party knowing that everyone was gone and something terrible had happened, but not yet knowing what. The whole thing honestly worked so well, and aside from that one moment, I really didn't run into the kinds of problems I often run into with text adventures with commands!
Awesome game!
