Expertise
One developer. The whole pipeline.
From the first prototype to live ops — design, code, balance, monetization and release are handled by the same hands, so nothing gets lost between departments.
Game & level design
Tower-defense and strategy mechanics refined over four generations of the series: turret roles, enemy counters, difficulty tiers.
Data-driven balance
Waves, economy and progression are generated with in-house tooling and verified by bot playtests on every difficulty.
Cross-platform engineering
One codebase ships to iOS, Android, Windows, macOS, Linux and the web — with platform-specific polish where it matters.
Monetization
Rewarded and interstitial ads with mediation, in-app purchases, premium and lite editions.
Localization
Up to 69 interface languages and localized store pages for worldwide launches.
Automated QA
Smoke suites with ~2,000 checks per build, regression tests and reproducible store screenshots.
Balance lab: threat ramp
Modern Defense HD · Level 13 · total enemy HP per wave, from shipped level data
Pressure grows ×450 across 14 waves, with a breather before the finale — tuned so a careful player wins and a careless one doesn’t.
