Hanae-san, just like Phasmophobia, everyone has a notebook. You check off the clues inside (blowing out torch, breaking of pots, etc.), and the notebook will help you solve the name of the monster that is in the tomb. You can then press the correct name in the door (10:51) and it will open. Grab the relic (the main objective) and escape to the jeep. This aside, I thank you very *VERY* much for playing this game, even if there was no Nihongo text for instructions. All your efforts was greatly appreciated. ありがとうございます! I do hope that you can play more of this in the future. There is more to it than stealing coins from your dead allies. XD
