For those that want to reach the end and not spend too much time figuring out how to, there are a few requirements.

1. Pick up a key at some point in the run.
2. Reach the "Insanity" Room, by going in the same direction 10 times, for example 10 right doors or 10 forward doors. At this point you will be given the first part of the key on a wall (FFRLLL)
3. From here you want to follow this key FFRLLLRFFRLRFRLLFRFL (F= Forward, R= Right, and L= Left)

It may look like you have rest a couple of times, but the room is slightly different, The painting may be upside down, The bookshelf may have been flipped, a table may be smaller or the bookshelf would have moved.

The ending is also just a room with 1 table in it and that is it. Sorry to disappoint. It turns out i wasn't returning anything for the last room, hence no ending.

There is another bug where the initial part of the key is wrong. It doesn't tell you about the red room that comes second.
