This is one of my favorite visual novels to date.
The writing and characterization are excellent. The twists and turns are ingenious.

You do have to be in the right mood to appreciate this - the warnings are NOT just for show. There are flashes of happiness in the routes, but none of them end well.

This is BY DESIGN.

The world of Particles of Reality: Obsession itself *IS* the worst case scenario. There are no happy endings.

You are *supposed* to be engaged and hopeful and then disappointed (or even devastated) by it all falling apart around her in the blink of an eye.

You are *supposed* to see Monika's world crash and burn on all sides no matter what.

The story being told is a TRAGEDY. Every. Single. Branch.
And you don't get a good tragedy by letting everyone live happily ever after.

Play this game when you want to watch train wrecks.
Play this game instead of doomscrolling.
Play this game.
