How we make a game

Four levels from idea to launch.

  1. Level 1★☆☆☆

    Find the fun

    Who is it for, and what do they do every minute, every day, every week? We sketch the core loop first.

  2. Level 2★★☆☆

    Playable prototype

    A rough version you can play in your browser, so we test the fun before polishing anything.

  3. Level 3★★★☆

    Build the world

    Levels, characters, art, sound, lessons and rewards, shipped in weekly builds you can play.

  4. Level 4★★★★

    Launch & live

    Release on the web or as an installable app, then updates, events and new content after launch.

FAQ

Questions from players & partners.

Do players need to download anything?

No. Every game runs in a normal web browser on computers, tablets and phones. Some can also be installed like an app, with their own icon, and keep working offline.

Can players play together?

Yes. Happy Duo is a two-player co-op adventure that two friends play together in the browser, with nothing to install.

Do the games work with touch?

Yes. Our games are built for mouse and touch and tested on phones and iPads. Kingdomfall also plays with a gamepad.

Can you build a game for my brand, school or product?

Yes. We design and build branded games, learning worlds and full game products. We scope it with you on a short call and show a concept before you commit.

Can learning games follow a curriculum?

Yes. Playwatch Academy is aligned to Head Start ELOF, Common Core, NGSS and CSTA, and Doris Academy follows Vietnam’s GDPT 2018 curriculum for grades 1–12.

How big a project is a game?

It ranges from a single playable lesson or mini-game to a full world with accounts, progression and an economy. We agree the first playable milestone together, then build in weekly versions you can play.
