Hey! Happy you like it, and thanks for the feedback :D
So, the intention is that whenever you step through a door, you immediately roll for how many doors are in the new room (after determining what's in the room). Exactly for the reason I think you pointed out, namely that you know where to go if you want to "run through" the room. But re-reading it, maybe I should indeed change the order so that you roll for doors before rolling what's in the room.
I was actually thinking just today that I want to revisit Neon Borg, improve it a bit, and get it into print in the final zine of the year. So if you have any other pointers, even minor ones, feel free to post them so I can consider them for the possible print :)
