A solid 6/10 experience.

Mandemon has an intriguing plot. The characters are alright, though after getting a couple endings you start to care less and less about them.

The biggest flaw in this game is the atrocious timeline mechanic. It's entirely for show and rarely useful, clearing with every reset and backtrack, meaning that if you aren't taking notes your out of luck. You can't go to individual scenes though the timeline. Check out Paranormasight for a better timeline mechanic.

Overall Mandemon is solid, good horror, and an interesting plot. Complete your first run blind and come back with a guide once you can;t figure out which choices to make to get all the endings.

No clue how this game has mixed reviews....
Its really good, kept me intrigued with a great and interesting story line, amazing CGs and art, and great voice acting. A true hidden gem and a steal at the asking price. This means if it's on sale, there's no reason to overlook this.
