5 stars: Excellent escape game! Solid, with some interesting puzzles. Nothing unreasonably tricky. Some have hints, if you are paying attention. Also, you do NOT need to know Japanese to play. Anything you need is in English. The icon is in Japanese on my phone, but that's all. So, don't hesitate to play!
5 stars: Simple escape game, but the puzzles (or rather the placement of objects you find) were clever and made sense, as opposed to trying every item on everything until something happens. Also, game is in English for those who fear not understanding Japanese language.
4 stars: Enjoyed. Nice game. Not too difficult but challenging enough to be interesting. This is one of the developers I like to follow. Looking forward to another game soon.
3 stars: Good game with logical puzzles. Not too difficult, didn't need hints. Rather short though but still worth checking it out. I like it that once a clue is utilised, you can't access it anymore.
3 stars: A bit on the cryptic side but still pretty enjoyable.
