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

Independent studio for Google Play
Valthera Conseil designs, develops and launches mobile games and Android applications — from first sketch to a live product on Google Play, and every update after that.
What we do
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.
From paper prototype to Play release: game design, Unity and Godot development, art direction, sound and balancing for touch-first play.
Native Kotlin apps built with Jetpack Compose and Material 3 — fast, accessible and designed for phones, tablets and foldables.
Store listing, screenshots and trailers, closed testing tracks, pre-registration, policy reviews and a staged rollout plan.
Crash triage, Android Vitals, seasonal content and analytics reviews, so the product keeps getting better after launch day.
Selected work
How we work
01 — 1–2 weeks
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
A playable or clickable build on real devices — tested early, so the expensive decisions are made with evidence.
03 — 8–20 weeks
Two-week sprints with a build on your phone every Friday. You always know what shipped and what is next.
04 — Ongoing
Closed testing, staged rollout, then live-ops: updates, events and performance tuning guided by real data.
The studio
“We treat every release like it’s the only thing a player will ever judge us by — because on Google Play, it usually is.”
Lucien Valthera — Founder & creative director
