Building ENCORE — a Rock-Stage Piano Rhythm Game for iOS

How I designed and built ENCORE, a touch-tuned piano rhythm game, end-to-end — and shipped it to TestFlight.

ENCORE is a rock-stage piano rhythm game for iOS — tap the falling notes in time to play real songs. I designed and built it end-to-end at Slopey Industries: gameplay, low-latency audio, UI, and the native iOS build.

ENCORE — main menu

What it is

  • A Play campaign that walks you through songs stage by stage.
  • A dice-driven Free Mode for quick, randomized sessions.
  • Audio tuned for touch — notes and hits stay tight even on a phone speaker.

How it’s built

ENCORE is a web game core wrapped as a native iOS app with Capacitor, using the Web Audio API for scheduling and playback. That let me iterate on gameplay fast in the browser, then ship the same core to the App Store toolchain. Signing, archiving, and TestFlight upload are automated so a new build is one command.
