In the game, you take control of a nameable protagonist and must travel through many different worlds with your yandere spirit companion, Kuro. The first version of the game has now been released, which is the otome version with a female protagonist and male Kuro, however, there are plans for releasing BxG, GxG, and BxB versions sometime in the future. Solipsism Reigns is fully voiced in English (aside from the protagonist) and is best played with headphones due to certain scenes containing 3D audio aspects. It contains roughly 175000 words. Estimated playtime when viewing all content and listening to all voice lines is around 22 hours.
You can romance Kuro but beware, he has yandere tendencies. He's perfectly capable of being kind and loving, but his jealousy can be a serious problem... Once that switch is flipped he becomes murderously possessive. Despite being a dark and twisted one, this is still a love story.
There are many bad endings but they don't mean game over, in fact, the more endings you view, the more of the truth you will uncover!
The game does not contain 18-rated material or sexual content, but it will include graphic descriptions of violence and some scenes of non-consensual kissing alongside some violent CGs.
There are multiple choices in each of the routes but the game is designed to be fairly easy to play without the need for a complicated walkthrough.
