This guide will basically go through the whole Any% route and what to do. Glitches will not be explained in this guide just to save reading time

Preperations

First of all. Start the game and play through the entire opening intro. All the way up until the final dialogue ("I'd better figure out how to get this collar off before then."). Once you are here, create a save file. This will be so that you can easily reset when you fail a run!

Hallway + Home EC

Start by heading over to the Home EC section of the hallway by clicking on the right side of the screen three times. Open the Options menu and select the Home EC door while still inside the menu. If it all works out, you should be kicked out of the Options menu and have the Home EC door selected. Choose the "Attend Class" option

When Brownie interacts with you. Select the "Be Nice." option as that saves 2 dialogue

Head on over to the right side of Home EC and select the top cabinets and the fridge for both the ingredients to make the cake.

Head back to the left side of Home EC and select the baking tool that are perched on Brownie's counter. This just bakes the cake instantly compared to having to talk to Brownie and selecting the "Give ingredients." option

Go to the right side and select the oven to bake the cake (select the "Bake Brownie's cake" option). And then go to the left and select Brownie to give the cake to her

Afterwhich. You can talk to Coco and convince her to dispel your collar. Select the "Manipulate" option and continue until the point where she dispels your collar ("His collar feels lighter!"). Since you would be skipping all the dialogue. This text would go by rapidly that you can't see it. A visual cue for this would be when Coco's heart changes. After that, right click 4 times and now you are teleported back in the Home EC hallway!

Library + Cafeteria + Gym skip + Ending

Head on over to the Cafeteria Hallway section and right click to open up the save menu. While there, interact with the Cafeteria doors and skip through Patches dialogue. Then, select "Back" and now Library and Cafeteria has been skipped entirely

While still in the menu. Select Options and click on one of the trash cans to get kicked out of the menu again. Head over to the Gym and play through the entire Intro Cutscene (Selecting either choices when dealing with Ginger doesn't matter as they both take up 7 dialogue). Once you are finished, right click and you are sent back to the Cafeteria hallway

Head into the blocked off hallway and select the "To Patches' Locker" option to grab Patches knife. Then select "To the gym" to meet up with Ginger. Select the "Kill her" option to obtain her fur and meet up with the gang outside

When outside. Patches will enact his master plan (even though he doesn't have the materials to do anything. But oh well the game gets messy when glitches are used). Select "What's best" and then "..." and lastly "Kill everyone" to end the run!
