Mibbi of Pebblewharf

  • In development
  • Ages 3 to 6
  • For tablets
All six friends gather by the maypole outside the button workshop for the Pebblewharf festival.
The festival, once every place in town is mended.

Each friend has one small power, and the limit is the puzzle.

Pebblewharf is a small tide-pool town with a wooden pier, a button workshop, a library in a shell, and rock pools. A child helps one friend at a time mend an ordinary problem: a sail-cart that will not leave, a thread knotted because everyone rushed, a button hiding in plain sight.

Whistle all three notes at once and the sail only flutters. Pick one, and it fills.

How it is built

  • No ads.
  • No chat, and no links out of the game.
  • No tracking. Nothing is sent from the device.
  • Spoken prompts, so there is almost nothing to read.
  • No fail state. A wrong tap gets a gentle retry.
  • Settings sit behind a parent gate.

Five friends and a tangle

  • Mibbi, a round puffin in a navy cape, standing on the sand.

Glowroot

  • In development
  • Cozy tavern game
  • For PC
Glowroot Falls from above: a turquoise pool, lily pads, and clusters of glowing mushrooms.
Glowroot Falls, in the first cavern.

You don't cook the monsters. You cook for them.

You inherit Nana's tavern at the mouth of the Glowroot Caverns. Each day you go down with a lantern and three kitchen tools, gather from the critters who live there, then come back up and feed a room of orcs, elves, dwarves and knights before the night is over.

Treat the critters well and more of them turn up at your door as regulars, until the dragon on the ridge books a table.

Bonks and sears, no blood. Critters leave a treat and hop home for a nap.

One day at the tavern

  1. Dawn Plan the day with Nana at the map table.
  2. Cavern run Gather by lantern light with a cleaver, an ember tenderizer, and a wok and skillet.
  3. Prep Set tonight's menu from what came back up.
  4. Rush Chop, grill, chill and stir, and serve before the guests lose patience.
  5. Closing Count the stars, the coins and the fame.
  6. Night Spend the takings at Nana's counter, then rest.

Who you cook for

  • Nana, a green-faced goblin grandmother in spectacles and a rose-red dress, on the tavern porch.

    Nana

    The tavern's goblin grandmother, and your mentor.

  • Old Smoulder, a brick-red dragon with glowing ember cracks and a white moustache, in the Ember Depths.

    Old Smoulder

    A big, grumpy-sweet old dragon. The pepper pods on the ridge make the scales itch.

  • Two lime-green Jellops beside Capling, a mushroom with a purple spotted cap, in a dim cavern.

    Jellop and Capling

    A lime jelly drop and a shy mushroom kid, two of the critters in the caverns.

Making learning playful.

We are a small, independent studio. We design, build and publish our own games, from a club of classic board games to 3D worlds with their own characters, places and rules.

Start with the play
Interaction, challenge and tone come before a feature list. When a game teaches, the lesson should be in how it plays.
Show the real thing
Every picture and every model on this site comes out of one of our games. Nothing is painted over or faked.
Say what is true
Available means you can play it today. A game still in development is labelled that way.

About the studio

Ideas

Notes from the studio on play, learning, and what the research does and does not support.

  1. The move you can hand to someone else

    Computational thinking is often described so broadly that any puzzle qualifies. A stricter test, from Peter Denning, is whether the next step can be carried out by a model without a person deciding what the step means.

  2. Publish chess. Leave the IQ claim out.

    Chess is on HD Games because the rules are deep and already shared. Reviews of school chess lessons do not show that the game reliably lifts general ability, reading, or mathematics once the comparison is fair.

  3. A finished round is not a course

    A 2013 review found a modest learning gain from serious games, and no reliable rise in motivation. The larger gains came when play was repeated and joined to other teaching. A round on HD Games is that loop. It is not a syllabus.
