Lil Portal Room is a room in The Binding of Isaac, added in the Repentance+ DLC.

A unique room available exclusively via the portal created by Lil Portal.

The contents of the room remain unchanged for the duration of the run, and it may be accessed from any floor by creating the portal again.

Any trapdoors created in the portal room will lead to the I AM ERROR room.

Internally, the Lil Portal Room is a copy of the starting room of the floor, and not an actual new type of room.

This room is not part of the playable area and exists outside of the map's boundaries.

The Lil Portal Room does not have an associated item pool.
