I'm sure that the big double doors in room 99 will be used for something but here's my idea for it.

After placing all fuses into the breaker box and figure getting burned, the player can back track to door 99 and go through the double doors leading to a door with no number.

After opening the door the player would see figure dose himself in the fountain, the player would crouch and crawl behind a nearby bench, figure wouldn't notice the player as the sound of the fountain and the rain would mask the door.

After gaining back control the words "The lights garden" would appear like how "the hotel" and "the mines" do. The lights garden would be a large open space in the shape of a flower with large fences (same fences as room 89) and a large door at the end of the stem that is held shut by 3 locks.

Figure would roam around the main plaza being a ever present threat making its way all around the garden.

Each lock has a challenge attached to it like a mini floor and each challenge will be located by a "limbo" statue each with a fire burning on its head. A red, yellow and blue fire statue would indicate which challenge you are doing.

The state with the blue fire, would be, the guiding light in the dark. This challenge takes you into a dark hallway only illuminated by the brief flashes of lighting. In the hallway gloombats and snare will appear forcing you to walk the entire hall in the dark needing to take it slow as to not step on snare, which will now release pharmons attracting the gloombats to the player for the next 3 seconds. At the end of the hall a lever can be pulled this lever will stop all entity's from spawning allowing the player to leave the first challenge. After leaving the challenge the blue fire would go out and a lock on the door would open.

The statue with the yellow fire would be, curiosity kills. This challenge would be a large hedgemaze with the main lever being located in the middle. Keys and vines would appear to block some of the paths with some of the locked paths being dupe, drawers and tool sheds would appear where keys and sheers will appear respectively, Timothy may appear in them and now clings to the player like giggles and bites poisoning the player making their vision blurry and if too many bites are taken at once the player will die (standing still and waiting for the posion to wear off is the best option). And Eyes will appear sometimes preventing players from looking around corners or looking down a path to see if its a dead end. After reaching the middle and pulling the lever a path would open leading to the entrance and all entity's would be disabled. After exiting the maze the yellow fire would go out and the next lock would open.

After 2 fires have gone out and 2 locks have been opened the fountain in the center of the garden would start to spew black goo instead of water. Seeks Eyes would now sprout from the ground beams of light indicating their line of sight. If the player walks into the line of sight the eye will shriek alerting figure to your position and figure will rush to you and roam the area in its frenzy state.

The statue with a red fire would be, with malicious intent. It would be a abandoned mini train ride with bridges that need to be jumped over (or sometimes in) small trains that can be hidden behind and dead ends that can be taken to extend the time you have to reach the end and use as a risky shortcut. Seek, rush, haste, blitz and A-120 will all appear but the player will be infinity sprinting. Seek and haste will constantly follow the player from behind, seek can be avoided by jumping into the water this will cause seek to loop all the way around if they are getting to close, haste will only be able to take one path and if you take the path haste doesn't haste will respawn at the start taking a different path until the player takes a path haste doesn't, the process repeating till the end. Rush will appear whenever a mini trains bell rings requiring the player to hide behind the train with the ringing to dodge rush, and A-120 will come from infront of you forcing you to take whatever path it is not on (you can run backwards if needed but it will let seek and haste get closer). At the end of the tracks will be the final lever and after pulling it all entity's will despawn revealing a working mini train that will take you back to the entrance. While on the train a cutscene will play where one of seeks Eyes will shriek luring figure towards it where figure steps on the eye, seeks goop covering figure and they stare at you before letting out a shrill shriek and making it's way towards you.

When you finally reach the entrance to the challenge the red fire will stop and the lock will come away the door fully opening looking to the side the seek figure will be running towards you lighting striking the garden setting it on fire setting up the final chase towards the door.

Fire will be on the path and falling trees will block your way forcing you to jump crouch and find the right path to the exit guiding light would be their to help you. After running through the final door guiding light and curious light would close the door on the seeking figure signaling the end of the lights garden and placing you in the same place where the mines ends. (Idk where it ends haven't finished it yet :P)

If anyone has any questions or suggestions I'd love to hear them ^{^}
