BackRooms 2D compiled is a small somewhat buggy game compiling the first three levels in chronological order(Levels 0, 1 and 2), below are short descriptions of them.
Level 0:
Level 0 here is the same as normal. There are no entities and you exit by a green blob.
Level 1:
Level 1 is a parking lot here with nothing different from the OG, the only entites are skin stealers and you exit via a exit door.
Level 2:
Level 2 is a maze of basement tunnels with boiling hot pipes and is no different from it's full game counterpart.
