TakeFive — Gomoku UFO Battle#

TakeFive is an Android game I built and published on Google Play back in 2014. It’s based on Renju (Gomoku), but instead of placing stones, a flying saucer (UFO) flies in and occupies the area — with missions that change at every stage.

I eventually pulled it from the store because of maintenance costs, but I still have a soft spot for the apps I made myself, and it felt a shame that it was no longer visible anywhere. So I stripped out all the platform pieces — scoreboards, in-app purchases and the like — and revived just the pure Gomoku game, its stage-by-stage missions, and the original images and sounds as a web widget. (I’ve written more about why I made the original game and what I took away from it in the TAKE FIVE dev story.)

No Look Keyboard — Type Without Looking#

No Look Keyboard — pick letters with 8-direction gestures

No Look Keyboard is an Android keyboard I built and shipped on Google Play back in 2012. It started from a simple frustration: “Texting on a shaky bus made me motion-sick — what if you could type using only the feel of your finger, without looking at the screen?”

Instead of tapping tiny keys precisely, you pick letters with big directional gestures (rubbing). Press and hold the input pad, rub toward one of eight directions to select the first letter of that direction’s character set, and rub back the other way without lifting to move to the next letter in the set. A plain tap (press and release) — without rubbing — switches the keyboard type (Hangul → numbers → symbols → Latin).

Piano Keyboard — A Keyboard You Play Like a Piano#

Piano Keyboard — a keyboard that plays a song as you type

Piano Keyboard is an Android keyboard I built and shipped on Google Play back in 2011. It was a reaction to my earlier No Look Keyboard, which was “conceptually interesting but too hard to use in practice.” This one aimed for low learning cost and immediate fun.

The idea is simple: turn the screen into a piano and place a letter on each key. Then typing feels like playing the piano. In the default mode (Song mode) the app picks one stored melody and plays its next note with each keystroke — so when you type quickly, familiar tunes like Twinkle Twinkle, Für Elise, or Canon come out. Composing a message becomes “a little performance.”
