Master math to save the galaxy!

A 90s-style RPG video game co-designed by a dad and his 6-year-old. Real Math. No slot machines. No dopamine traps. No ads. Just a fantastic little town that needs saving.

A Pixel-Art Educational RPG

 From the outside, Sumville looks like any small city: coffee shops, school buses, a guy who runs a key shop and definitely isn't a wizard. But something is off. The bakery's been giving out the wrong change for weeks. The bus routes don't quite add up. Yesterday, a kid's homework looked back at him. The adults don't notice anything. It's up to the kids to save the world by paying close attention to the strange stuff adults ignore.

You play as a small hero with a backpack, who can multiply faster than he can tie his shoes. You'll wander the city, befriend a kid and his rabbit who want to reach the stars, a zen-master snail, and a hip-hop chicken — and battle Multiplication Monsters in the supermarket parking lot. Along the way, you'll master the lost art of Concrete–Pictorial–Abstract math and put the numbers back where they belong 

Why We're Making It?

Active Learning, Not Passive Scrolling

Most kids' math apps are dopamine traps wearing cartoon costumes. My son deserved better, so we started building Neighborhood Number Heroes ourselves. We follow two strict rules:

1. It has to be genuinely fun

This is a game told from a 6-year-old's point of view. He draws the characters, invents the situations, and decides what's funny. I turn his sketches and stories into the kind of indie game I grew up on — EarthBound, Stardew Valley, Undertale, Hollow Knight, Terraria.

2. It has to teach real math

Singapore Math's CPA method. Deep conceptual and visual understanding. The kind of skills that hold up when the homework starts looking back. By finishing the levels, your kid actually masters different math topics and actually strengthens his understanding.
