It's strange being northern-hemispherian and seeing green trees outside at Christmas. You have now 3 of 20 rooms... TBH I don't think that's much. Or let's say maybe 20 rooms in total are a bit too much for such a short comp. I guess you have a plan B for when you have to cut some rooms?
I agree completely with Steve - gameplay before anything else. If it's a little rough around the edges but a properly playable game by the 23rd, then I can live with that.
