Run Marco!
Launched 2014 · Personal revival underway
Product challenge
Allcancode is part of my history. I decided to revive Run Marco to keep the company’s legacy alive: a coding adventure where children guide Marco or Sophia through puzzles, assemble instructions, and learn through play.

The original game and its revival
I built Run Marco as Allcancode’s first shipped product, bringing together game design, visual programming, artwork, and testing with children and educators.
The game launched publicly in October 2014. Feedback from classrooms and our time at Imagine K12 in Silicon Valley shaped both the game and the tools around it.
I built visual authoring tools so that game content and rules could evolve on a shared foundation. That work later informed the Allcancode application development platform.
I decided to return to Run Marco personally as the legacy of Allcancode. I am refreshing the standalone game’s interface and play flow while retaining the original characters, artwork, and puzzles.

The original adventure
Run Marco has its own product history, before the later Allcancode platform. The original title screen preserves the game’s illustrated world and characters.
Evidence and lasting outcomes
A coding game that remains available more than a decade after its original launch.
A direct route from a shipped learning product to the authoring tools that helped shape Allcancode’s later platform.
A personal revival that keeps Allcancode’s legacy available to a new generation of players.
