It's entertaining, short, adventure, puzzle quest game with many gruesome deaths, little bit of nudity and few plot twists.

Game is straight forward - there is only one way to kill each person and you must find all items to do it. Even with all quest items, it may take some time to understand what and where is required to do, but luckily there are guides for that.
Don't expect open world here - mansion and garden is all you can explore.

Graphics even on Ultra High left me unsatisfied. You may encounter some bugs, restarting chapter will fix that.

There are 2 endings. First is easy, 2nd takes some time to do it right, but will reward you with more satisfying ending, a la horror movies.

Don't expect too much, this is no AAA title, but good for indie developers.
Buy it on sale and you won't regret it.

P.S. Don't let your kids play this.
