Spooky greets the player in the first room, "Room 0"; her cute appearance and humorous dialogue may lead the player to believe that this is going to be a simple game to poke fun at other horror game clichés. In the first 50 rooms, no monsters or death traps appear, and the only scares are Specimen 1. This may cause the player to completely drop their guard and expect a harmless parody. The first and only indicator that things are not as they seem are notes that appear randomly on Specimen 1 and furniture which tell ominous accounts of the previous travelers of the mansion. Once the player reaches Room 50, which is an elevator, they are rewarded with a save point before pressing the button and continuing to the next floor. This is where things begin to change.
In this section, things start to change, as dark maze-like rooms surrounded by abysses begin to appear, as well as out of place objects such as the Brainframe. However, the real scares don't begin until the player reaches Room 60, a large room with a mysterious black and green puddle in the center and a note on a table that reads "Spouting, Splashing, Soaking. Innards, Ingest, Invoking. Nailing, Never, stops the Choking" in red text.
Once the player puts the note down a loud choking sound is heard; this is the indicator that Specimen 2, the first hostile enemy in the game, has appeared. It must be avoided at all costs. The player is then chased by Specimen 2 through several rooms, which during the pursuit have black and green puddles on the floor that slow the player down and increase the chances of getting caught. Once the chase ends, the rooms continue as normal until Room 100, which is another save room/elevator.
- Room 0, where the player meets Spooky for the first time. She explains the main goal and then flies through the ceiling.
- Room 50, where the player finds an elevator (which is a Saving Room). The player can also find the 'Romantic' notes there. To continue to the next floor, the player must push the "down" button on the far wall. Then a door leading to Room 51 will appear.
- Room 60, a room with a green puddle in the middle, and a note on a table at the other side of the room. After reading this note, Specimen 2 appears and chases the player for the first time.
