Booting up the game, you start in Lisa's room. You can interact with the items in her room, but they only provide flavor text. Exit her room, and walk down, through the hallway and into the living room.

Here, Marty is watching the TV. Walk around the back of sofa Marty is sitting on, so that he doesn't see you. Walking down the right side sends you back to Lisa's room. You can then exit the house, and walk directly left, until you find a maze-like path, directing you to Marty again.

Interacting with Marty has him ask you "You're tryin' to run out on me are you...?". Answering No will prompt him into saying "Then go home, coward.", whilst answering Yes will have him say "You can't run forever. / You're wasting your time.", which will then teleport you to the Lobby.

Once you have been teleported to the main hub, you're greeted with a carpet and candles decorating it, indicating for you to go up. Here, you're told what specific buttons do: ESC to go to your inventory and SHIFT to return to the lobby.

In the lobby, there's multiple doors/ladders/etc. for you to enter, a TV which requires a VHS tape and a bed where you can save your progress. The places you go to are as follows:

• Red Door - The Town
  
• Iron Ladder - The Blank Road
  
• Tin Door - The Mansion
  
• Rope - The Rope Room
  
• Sand Door - The Sea
  
• Red Ladder - The Bile Road

In this room, there is a rope immediately to your left. Climb up that rope, and you'll see a rock puzzle and a box. Open that box, and it will give you the Work Gloves, allowing you to push the rocks around the area. There's a few more rock puzzles and ropes to climb, and once you see a Marty in the water, you've made it into the town area.

Go directly up and to the left a little; you will find a concrete house. A Marty is found in here, asking you to fetch him some rum. Leave the house, and go to the bar located eastwards to the house. In here, there are Martys having a rave. Go up and interact with the Marty touching the wall on the top right - he's blocking the door you need to enter. Once there, another Marty is in the bathroom, this one being the bartender. He gives you rum, and you're free to go back to the concrete house. The Marty in this house gives you the Red Key to progress.

Behind the house, there is a hidden path leading to another Marty, who gives you a Banana. This is required to get one of the VHS tapes for the TV in the Lobby later on.

Once you have the Red Key and the Banana, head north-west to a gate and unlock it. The Red Key breaks after use. You'll then find yourself in a red basement, followed by a few rock puzzles. The first two are relatively easy, and the third one you'll need to move the bottom left rock to progress. Walk down - there's another Marty. He asks for your Banana, in which he gives you a Banana Peel in return. Go down and back up the stairs to a new area.

Going up the rope leads you to Tricky Rick - he says some profanities towards you, and you'll have to kill him to progress. Go back and then down the grey stairs. Go straight down and then to the left a little to find a box which contains a Razor. Then, go back up to where you came from, and kill Tricky Rick with the Razor. A bridge appears after, so walk over it. Another Tricky Rick appears, taunting you. Interact with the candle to go back to the entrance, and then back to the lobby.

Make your way through the Sand Door and head immediately right - there'll be a Marty who exchanges your Banana Peel for a Napkin. Once obtained, head north and to the left to find a patch of land surrounded by Martys. Hack away at the reeds with your razor and go down the stairs. You are now in the spider cave. Enjoy! :)

Going right and down is a trap, and going back spawns a bunch of Marty Spiders, sending you back to the entrance. Instead, head immediately up. Once you see flashing squares, Marty Spiders will spawn and either chase you or move in a static order. There are certain checkpoints in the cave, so you won't be sent back to the immediate start every time you end up getting caught. Time and patience is key, so don't get too distraught when you get caught. There are certain safe points outlined by the spiders's movements, so utilize them as best as you can.

After the main few puzzles, you'll find dead Marty Spiders leading all the way up to a red ladder. Go up, and pick up the Bottle of Pills found in the room. Press SHIFT to return to the lobby, and head back through the Red Door. Interact with the candle by the door and force the pills down Tricky Rick's throat, then head down the stairway. You will find a sword, and then hit SHIFT once more to head to the lobby.

The Iron Ladder in the lobby leads to the Blank Road. Head through the door immediately north, which lands you in a blank room which appears to be infinite, but it repeats every few acres. Exploring the room and interacting with the objects and Martys spawns a heart over Lisa's head.

Go immediately down and to the right a little, and you'll find two statues. Walk between them to change the landscape, making it horrible and bloodied. The Martys in the room become horribly disfigured and make a familiar sound when interacted with. Head north-west to find a newly-opened staircase, and pick up the Plastic Bag that's embedded between two crosses. You can go back from whence you came, or just hit SHIFT to return to the lobby.

The Red Ladder leads to the Bile Room, right after a pair of rocks. The houses are covered in vomit and flies, and the Martys in the area are once again horribly disfigured (well, most of them.) Heading up and to the right a little will lead you to a Marty that looks like he's jerking his hog into a pond. Interact with him to give him the Napkin, in which he gives you the Finger in return.

Head immediately left to a red house. There's an entrance on the left marked by the ground for you to go through. Interacting with the cross in the middle of the room opens a hidden staircase in the top left of the room. Down here is another cave filled with Marty Spiders. This section is significantly harder than beforehand, but the second section allows the use of rocks to block the spiders' paths and make it easier to traverse through. Do be warned that it is possible to softlock yourself in this area, due to the nature of the spiders further on. Make sure when using the rocks, you are squishing the faster spiders between it and the wall.

Once you have traversed through and gone up the stairway at the end, you will find yourself in a penis-shaped room. Lovely. To the right, another Tricky Rick is found. Use the Plastic Bag on him to suffocate him. He will drop a VHS Tape - titled "Tricky Rick". Interact with the candle to the left to go back to the entrance and to the lobby.

Briefly go back up the Iron Ladder to the Blank Road once again, and head down the ladder to the right. Interact with the Marty in the room and he will give you his VHS Tape - titled "Marty" in exchange for the Finger. Head back to the lobby.

Head through the Tin Door in the lobby. To your right is another statue. Interact with it, and you will use the Sword on it. Here, you'll be teleported to the Mansion. A very spacious area, head through the door and then straight down - you'll know you've progressed once the song changes from The Royal's Call to The Sireen's Call. Head directly right into the door on the end, and then into the door on the right side of the room. At the end of this hallway, walk in through the double doors.

This room contains a horrific image of Marty. To proceed, head to the left of Marty and go inside him. Here, you're transported to a red room. Heading directly north will show you a mirror image of Lisa. Interact with her, and she'll turn into Marty, and then you will teleport back to the lobby entrance. Pick up the Necklace that spawns at the bottom of the screen.

Hit ESC to go to your inventory. There's a room bottom right; enter, and interact with the candle. You'll be teleported to what looks like Lisa's room. Head out and through the hallway, to a black void. Going north shows Marty, standing naked. He tells you that you're wasting your time, and you are then teleported to a white void.

Head straight left. A VHS Tape - Mom's VHS is there, so pick it up. Then, walk in any direction. Marty begins to monologue, and the screen turns red for a bit until it fades into a void filled with Marty's face. "THE END" appears shortly after.

Interact with the TV to play the tapes. Marty's tape spawns you as Marty in a white room. Heading north, you find Marty and Lisa playing with a tea set. The other Marty seems non-abusive; what could've been. Hit SHIFT to go back to the lobby.

In this VHS, Lisa is spawned in an area with pink grass. Hop down the cliffs and head right to find Tricky Rick. He tells you vaguely NSFW phrases, indicating the sexual abuse Marty put Lisa through. Once he's done talking, you're teleported back to the lobby.

When you pick up Mom's VHS, hit SHIFT to return to the lobby. Then, interact with the TV. You're then teleported to a room with Marty's face plastered everywhere once more. Head north, and you'll find Lisa's mom. She talks to you, apologizing, only to turn around and reveal herself as Marty, indicating that no matter what Lisa does, her memory is nothing but him. "GAME OVER" is plastered on the screen, and you're returned to the title.
