How I work

Gameplay systems

Core loops, economy, progression, tutorials and touch controls, with content in ScriptableObjects.

Performance-first code

Spatial hashing, batched sprite rendering and no per-frame allocations in the simulation loop.

Playable ads

Built to the networks' size limits, with difficulty checked by simulating random play.

Testable code

Logic kept separate from the engine, automated tests, and builds checked on real phones.
