Alphabet PWA
A game for learning the Korean alphabet, Hangul, for the first time. I built it for Ottiya as a progressive web app, as lead developer in a team of five.

The brief
- Fourteen consonants, each written seven times
- Five tests that match a consonant with its sound
- Dr. Coli, a broccoli, shows how each one is written
- Points, levels and coins, with a shop to dress the mascot
Learning a letter
From the start screen to a list of challenges, one per consonant. Before a letter is written, Dr. Coli shows the stroke.
Tested with children
- 16
- 2
- 7
“I want to learn Korean so I can talk it with my parents.”
Practice and reward
Each consonant is written seven times. The first prototype asked for more and the children got bored; five turned out too few to remember the letters. A finished letter earns points and coins, and the coins buy the mascot a new outfit, which is where the children spent most of their time in the test.
“If you make it, you know, game type, we will use it. I think you did a great job.”
