What we are building

Gameplay

Two modes: one circle in portrait orientation and two circles in landscape, with a shared score and separate targets for each side. The player starts with one heart; completing each 30-second phase restores one, up to a maximum of three.

Progression

Successive phases speed the pulse up and narrow the target. An ordinary hit is worth 10 points; a chain of perfect hits multiplies the base up to eightfold. Experience points earned build the player level, and they neither affect difficulty nor offer paid shortcuts.

Privacy and offline play

All gameplay works without a network connection, and progress is stored only locally on the device. No accounts, no analytics, no payments.

The game is free and funded by advertising. A full-screen ad can appear only after a finished run — never during play, a pause or a menu — and its frequency is capped inside the application. In Europe we ask for consent before requesting any ad; refusing blocks nothing in the game. Details in the privacy policy.

Build quality

The game logic is separated into a module independent of Android and covered by unit tests; the application layer has its own set of interface and lifecycle tests. State persistence is versioned, with safe restoration of older formats.

Accessibility

Native, labelled menu controls, an option to reduce decorative animation, a haptics toggle, contextual help for every setting, and a slower practice mode with its own personal best.

Technology

Kotlin, native Canvas drawing, Android SDK, Gradle. No game engine and no third-party graphical or audio assets — the entire visual layer was created for this project.
