About This Game
Design the wrong. Combine the errors. Prove what’s possible.
Detailed Description

Welcome to the world of errors!
A light, cute, and relaxing logic puzzle that begins with the simplest formulas.

Complete each formula to reach the target error value and clear the stage.

The game offers 15 levels and 128 handcrafted stages designed to challenge your logic and creativity.
Errors breed more errors, and tiny deviations open new paths.

From these errors, beings known as Eri and Kori are born — and they never forget the rituals of their creation.
Recruit supporters to accelerate your progress toward the target error.
But beware — some number blocks come with their own constraints, adding unique conditions to your play.
Start with small calculations, and watch as they grow into a complex flow of logic and cascading errors!
