Greetings. It is highly recommended that you download Eleval's practice tool and use the door skip that comes with his tool. It is significantly faster than the FluffyQuack mod. While we do not have an exact time save between the two mods, saving close to two minutes is generally agreed upon. It is on the resource page. Myself and several other runners have tested it thoroughly and there are no issues such as crashes. Eleval plans on updating it with a few more features. IF you have any questions, dont hesitate to ask. Happy running!
