Here is a guide to introduce you to Project Kat speedrunning

translations: Korean is by far the fastest translation to version 1.2.1 but Japanese is the fastest translation in this game but it is for version 1.1.0 compared to version 1.1.0 it has three free texts that must scroll normally before skipping them to read it see this guide https://www.speedrun.com/project_kat/guide/i99ft

skipping dialogues: it saves a lot of time because dialogs skip even faster so you can get the best time video: 0:40

route:

1. route is to get the curtains you have to enter the theater there are three ways

2. obtaining a lockpick - it's in the first room, the 2nd bench on the left, downstairs, then use it to start the mini-game with opening the door (it's faster)

3. you can drop the purse on the floor and take the key to do that you have to interact with the door to the theater room when you get the key use this key in the theater room

4. you have to find a book for girls you have to interact with the door to the theater room then ask the girls for the key and instead you have to bring them the book is in the third room in the 4th bench upstairs there is the book then give it back to the girl and then you will get the key and use it in a theater room (it's slower)

5. route is through the door going up there are 2 ways to go

6. in the case of the rout with getting covers, you can use the lockpick again to enter the room (NOTE this route is very difficult and many runes will die on it, but it is faster, if you don't want to lose your nerves, use the 2nd method)

7. interact with all the doors then come to the point where there are stairs to the door you want to enter then go around one way if the dialogue appears it means that you have reached the key, take this key and then open the door upstairs
