// about
Hi, I'm Kevin Oliveira — a solo developer building web apps, backend APIs, and games under the banner of KO Labs.
I care about clean code, good UX, and shipping things that actually work. Whether it's a mobile app, a REST API, or a pixel-art game — I build it with the same attention to detail.

Space Invaders
A retro pixel-art arcade shooter. Blast through 12 worlds of invaders, grab power-ups, break the armor of a unique boss in every world, and chase the high score.
Just Digits
A native iOS number pad keyboard. Pick it from the globe menu whenever you need digits, even in a text field that shows letters.
Pockarty
A cozy pocket RPG for iPhone. Send a little fellowship on woodland expeditions and follow along from the Lock Screen and Dynamic Island.
Gloopfall
A maze chase where you drop the walls. Steer a hungry slime through a pixel maze and place falling blocks to trap the Mites hunting you.
Lanterns & Shadows
A calm logic puzzle for iPhone and iPad. Light every street of an old town without letting two lanterns shine on each other — 200 puzzles plus a daily one.
Constellations
A calm logic puzzle for iPhone and iPad. Join numbered stars with lines that never cross, and figures from old myths light up in the night sky.
