Cool story, decent puzzles. English translation is pretty bad, but at least good enough to follow what's happening. Unskippable ads between stages (so 6, total), but that's pretty much it. Didn't feel excessive or intrusive at all. Devs have to get payed somehow, right? All in all, very good.

We are glad that you enjoyed our game. You can also play the original offline room escape version of “The secret of the hidden room” in RoomESC in Seoul, Korea. All the developers are working hard to get to the next series, Frankenstein. We hope you are looking forward to our next series “Frankenstein” as well! 'v` Thank You! :)

This game is really good: the story is gripping and so relatable, the puzzles are not too easy and quite diverse so not to bore the user, the 3d graphics are brilliant. Only complaint is the English translation that sometimes makes understanding the goal of a puzzle a bit too difficult. Definitely recommend.EDIT: replayed, it's a 5. It is really awesome, and a heartrending subject (not a 'fun' one, maybe a warning would be useful to alert people)

Absolutely loved it. The storyline is good and the puzzles are brain wracking but not too hard to figure out. The only downside, as mentioned in some of the other reviews, is the sometimes poor grammar with the occasional typo but it doesn't affect the game play. Well done devs. Looking forward to what's next
