Start a new game for the first time.

Do Keenarnor's second route, which is gotten via having low affinity points. (AKA accuse him of murder a couple times but also don't get too attached to Roobit)

On Day 5 of Lamp's route, deny her confession. This gives you the bad ending.

On Day 3 of Chris's Route, answer "AAAAAAAAAAA" to all of the poem decisions.

On Arimnae's route, if you have 0 affinity points, a new option will appear when you have to decide if its your birthday or if its Christmas, "♥♥♥♥ u arimnaes". Choosing this gives you Arimnae's bad ending.

Complete the true route.

On Day 4 of Arimnae's Route, when Kiane leaves to go use the bathroom and Inner Kiane stays with Sensei, screenshot 4 times before she gets out of the bathroom.

On Day 3 of Keenarnor's route, ask Roobit to recite the elements. When she asks which she missed, answer Antimony.

On Day 4 of Lamp's route, dribble incorrectly 5 times in a row. You will be stabbed with a basketball and also get a game over towards your Master of Disaster progress.

On Day 4 of Chris's route, during the fight with Brain, each time its your turn take a photo of her. Keep doing this until she dies.

On Day 4 of Chris's route, during the confrontation with Plungersei, answer "this is the sensei route". This will automatically put you into Day 3 of Sensei's route. Continue like normal. When you get to Day 5, choose to talk to Plungersei. This gives you Chris's bad ending.
NOTE: I am not responsible to any damage to the timeline this causes.

On Day 4 of Chris's route, defeat Brain, Arimnaes, Boo, and lose against Sav by ONLY defending.

On Day 5 of Arimnaes's route, wait the full 30 minutes of Anti-Pizza Game.

On Day 2 of Keenarnor's route, order a pizza from Sav. When you're asked to give him a rating. Give him a shooting star. This will ♥♥♥♥♥♥♥ kill him. Continue to get a game over, or roll back and instead of ordering a pizza from Sav, say hello back. Continue through Keen's route as normal with affinity until you have to tell a secret to Keen and Boo. Choose "i am sav". This gets you Keen's bad ending.

On the true route, choose to go back to work. Roobit will come in to save you from Arimnaes. Choose to sacrifice yourself to save Roobit.

On Day 5 of Sensei's route, choose to talk to Cousin Stankel or whatever his name was I forgot. Do not forgive him for his horrible pun. This gives you Sensei's bad ending.

On Day 4 of Chris's route, buy the Very Hot Sauce from Warped Merchant. Use it at full health during Brain, Boo, or Sav's fights.
