Hey, thanks for playing it!
Yeah it says at the beginning of the room choosing that you can only explore two per run. It's done to incentivize replayability and there is a sort of guess game at the beginning to try and understand which room are going to be visited by who, so you can spend time with your favorite character (sasha is a bit of an exception). After two rooms, the game shows how much you've "clicked" with each person, and from your answer I guess you had the "bad ending" where you click with no one and go home alone ahaha
I also understand that probably we should've made more clear that you finish with two rooms and maybe a better end screen would've helped.
We are very much amateurs so, thank you again for playing!
