We completed The Truth of Osaka High. Great escape room. We've completed about 10 rooms in different cities. This one ranks up there. Our fave is still Escape Games Canada (in North York) but this is a very close second. There four of us. A good number as the puzzles are linear. They recommend six but with six you'll probably have people standing around. Good use of technology. Not an overwhelming number of puzzles so success is achievable but the puzzles are clever so it is challenging. We had to ask for a couple of hints. Thematically a little scary but not too much so. No padlocks which was a change from other rooms we've done.
Side note. Little else at the facility other than a few board games and a small table so don't plan to hang around before or after your escape room.
Staff are not the most enthusiastic or engaging.
