What's a good Android rhythm game for offline play?

Piano Tiles 2™ is a rhythm game designed for casual players who value offline accessibility and straightforward mechanics. The gameplay involves tapping black tiles as they descend to the beat of various piano songs, with no complex timing windows to master, making it ideal for short breaks or travel without internet. Specific features include multiple modes like classic and zen, a broad song library spanning classical to pop genres, and a nostalgic interface restored from earlier versions. Users report that the offline capability ensures uninterrupted enjoyment in scenarios like commutes or flights. However, the experience is impacted by a monetization model reliant on frequent video ads and a subscription for ad-free play, which some find overly aggressive compared to one-time purchases. Despite this, the controls are responsive, and the visual presentation remains clean with piano-themed aesthetics. Minor imperfections include occasional ad placements between songs, but the core gameplay delivers a reliable, low-stress rhythm experience for offline use.
