What we do

One studio, the whole journey to Play.

Strategy, design, engineering and launch sit in the same room. Fewer hand-offs means fewer surprises — and a product that feels made by one hand.

01

Mobile games

From paper prototype to Play release: game design, Unity and Godot development, art direction, sound and balancing for touch-first play.

UnityGodotPlay Games Services
02

Android applications

Native Kotlin apps built with Jetpack Compose and Material 3 — fast, accessible and designed for phones, tablets and foldables.

03

Google Play launch

Store listing, screenshots and trailers, closed testing tracks, pre-registration, policy reviews and a staged rollout plan.

04

Live-ops & care

Crash triage, Android Vitals, seasonal content and analytics reviews, so the product keeps getting better after launch day.

How we work

A build on your phone every Friday.

01 — 1–2 weeks

Discover

We meet your players or users, map the core loop or job-to-be-done and agree what success looks like on Play.

02 — 2–4 weeks

Prototype

A playable or clickable build on real devices — tested early, so the expensive decisions are made with evidence.

03 — 8–20 weeks

Build

Two-week sprints with a build on your phone every Friday. You always know what shipped and what is next.

04 — Ongoing

Launch & grow

Closed testing, staged rollout, then live-ops: updates, events and performance tuning guided by real data.
