I got far enough along in my Descended from the Queen + ECB mashup to give it a try last weekend. It's still pretty rough around the edges but workable enough we were able to come up with a fun story, put together the clues and make our "theory roll". I think it would probably benefit from a few player-facing options to control the clock / position, but I'm not sure how to build those in yet.
I also want to write a few more prompts and missions to mix it up a bit.
