What it is
Mathio Bros: The Starfall Isles is an original single-player platform adventure rendered in Canvas 2D. Four cosmetic heroes with identical physics cross six deterministic hand-built isles with plateaus, ledges, walls, checkpoints, and vertical climbs.
Optional power blocks pause play for fourth-grade questions covering multiplication, division, fractions, place value, rounding, measurement, area, perimeter, elapsed units, and angles. Correct answers unlock abilities such as higher jumps, gliding, electric protection, or shields.
Each isle ends with a guardian that must be defeated before its star gate opens. Collected stars also enter a device-local bank that can buy stronger temporary powers without reducing per-isle scores.
The dependency-free Node server delivers vanilla JavaScript and original procedural art and sound. The Games Hub supplies the display-name greeting, while unlocked isles, hero choice, best scores, and the star bank remain local to the browser.

Inside the project
Capabilities
Key features
Fourth-grade math powers
Correct answers unlock temporary movement, defense, and electric abilities without adding a timer to the question.
Four cosmetic heroes
Pip, Fern, Nova, and Mochi share the same fixed collision and movement rules.
Gate guardians
Every isle ends with a multi-hit guardian whose defeat opens the final star gate.
Local star bank
Earned stars persist on the device and can fund stronger temporary powers without touching the Hub wallet.
Under the hood
How it works
- 1Vanilla JavaScript runs a fixed-step platform simulation and paints original procedural characters, levels, enemies, and effects to Canvas 2D.
- 2Deterministic world data owns bounds, terrain, checkpoints, respawns, gates, and guardian arenas for all six isles.
- 3A question generator creates grade-four problems, explanations, hints, and bounded recent-question history.
- 4Browser storage preserves unlocked levels, hero selection, best scores, question history, and the device-local star bank.
