The route for the 100% glitchless it follows along the any% with the deviations I have mentioned, To reset steam achievements to make it more obvious make sure to load into the game and enter debug mode (ctrl + 3 backspace[press backspace three times while holding control]) then with debug mode active hold alt and press 9 on the numpad with numlock on and it shall reset your steam achievements (Or use SAM if applicable). I have written this in sections of text with each next one ending on either an achievement or step leading up to an achievement.
Note: This is following Maky's Steam V1 100% 5:28 no load WR. There have been potential time saves talked about but never successful or implemented. There may also be interjections of other routes followed by other people if there is a chance they may be faster or unknown.
Start off as usual to any% but at the logs constantly go in and out of the coast only grabbing the group of 3 going from Closest, Top, Bottom until you get 42 logs, if you are able to count it as you go once you reach 40 only grab the closest and the bottom ("Pocket Forest").
Next head home but grab the AA batteries on the desk on your way to bed. Sleep, wake up and walk down to the bus stop. Take the bus to the Forest and enter the tower, grab the dagger in the table and head up to the apex of the tower to grab the key.
Take the bus back to town and then head to Dary's. Talk to her and get the key back. Next head out of the house and go right, to the back of the police station and through the trees grabbing the documents as you go by. Talk to Chelsy and give her the documents (make sure she sits down or else Chelsy and the clubgoers despawn, invalidating the run). Head outside and meet the clubgoers ("Police Assistant").
Walk by the bus stop and to the road house (don't take the bus there) and put the batteries in the radio ("Radio Enthusiast"). Go back to Mondealy and take the bus to the forest and enter the tower once more, grabbing the tiara on your way down ("Grabby Hands"), and then get kidnapped.
Wake up, let the guard (Hass) free you and then continue along regular Any% route, pushing the bat in the Pagoda on your way out ("Provocateur"). Leave, head home, and then enjoy a feast.
Grab your items and skip Riley's text, interact with the door before she starts speaking then interact again before she starts speaking. (Note: In Maky's WR, Michael does not re-enter the room to grab the Plush which can allow for you to potentially skip bad RNG at rufus but only Zorai has ever implemented this) Leave, talk with the pair at the bottom of the stairs (if they spawns, if not exit and re-enter), just spam it doesn't matter what you enter. ("Simple Questions - Simple Answers")
Enter Corsic's Room and interact with the bed (you don't need to save but feel free to do so) ("Need a helping hand to save?") Follow Any% to Froga, grab the Plush at the stalls at the top of the beach and next to Eliza. Make sure to get the plank from Froga.
Walk to Rufus' and enter, here you can either immediately head down ("Euclid Minded") and keep on interacting with notes until you interact with the 8th one ("Stories from the Other World") and then using the code (2 Right, 2 Up, 4 Right, 1 Up) to get the keys ("Eavesdropping") or you can just use the code to save the game and if you had previously grabbed the Plush later, after doing Shy also grab the items in Rufus' house for the achievements.
Next after saving in Rufus' house go and talk to Shy and ruin the couple's date ("Heartbreaker"). Then reload the save and grab the ingredients and a meal to give to Shy ("Savior of Shy").
Head back to Froga with the ingredients and get the "potion" and head back to the Castle. Grab the fourth Plush in Riley's room (if following Maky's route) ("Ah, My Muse"), then leave and stop timing when the screen fades black after saving in your room.
