Japanese indie developer Caramel Column has announced Prolegomena, a new “choose-your-own-adventure” visual novel.

Prolegomena, which has the lengthy title Prolegomena To a Hyperdimensional Interface That Will Be Able to Manifest From Three-Minute Interchanges, is in development for Windows PC (via Steam), with a release set for sometime in 2025.

Here’s a rundown on the game, plus its reveal trailer:

Can you hear me? Actually, I’m not sure if “hear” is the right word. Are my words reaching you?

…

Unfortunately, I can’t tell if you’re responding. Perhaps the communicator is malfunctioning. Still, I’ll trust that my words are getting through to you and tell you this.

This is a collaborative experiment between you and me. Not knowing what kind of experiment it is must be unsettling for you. So, I’ve summarized the key points for your reference.

Game Features

• You and I can engage in continuous interchanges for approximately three minutes.
• My voice will reach you fully voiced.
• The outcome of the experiment depends on the content of our interchanges.
• Interactions will primarily occur through an interface called “choices.”
• However, I might require proof that you are an existence beyond dimensions.
• If that happens, I want you to respond through an interface that transcends choices.
• Even if I perish, I want you to continue the experiment. 

That last point caught your attention, didn’t it? There isn’t enough time for me to complete the experiment.

But if you cooperate, the experiment can reach completion.

After all, you are—

Time’s almost up—

Join the experiment—

I’ll be waiting—here.
