This guide will help you attain the Speedrun achievement for this game. Using this guide I managed to clear the game within 24 minutes. It had cost me about 3-4 runs to get all the locations memorized.

I will post the video I made along with a quick rundown on the items required per section. I hope it will be useful.

For a shortened guide you can visit my forum[forum.jorigaming.com]. This will list only the items / intuitions you need to collect per room instead of a fully written walkthrough (Handy for those that memorized the item locations).

• Do not save, it takes a few precious seconds away and some people reported not getting the achievement after loading a save where they made good time
  
• The chance is high that the first house change occurs after witnessing an event
  
• You do not have to force the 2nd change in the house until you actually go into the Grotto
  
• Losing Sanity often helps triggering the house changing the 2nd time
  
• Do not pick up unnecessary items, it only ticks some time away
  
• If you really can't make it on the extended edition you can use the normal edition. It is shorter with less rooms. However I do not have a complete guide available for this.
