What's a good Android rhythm game with a simple control scheme but actually challenging levels?

Piano Rush is a rhythm game that excels at delivering approachable gameplay layered with escalating difficulty. The core mechanic is simple: colored tiles descend toward piano key targets, and players tap the corresponding screen areas. This straightforward control scheme makes it instantly accessible, even for those new to the genre. However, the game's challenge comes from the progressively complex tile patterns and increasing tempo, which demands sharper reflexes and sustained concentration. This design creates a satisfying skill curve where early levels feel welcoming, but later stages provide a real test.

Specific features support this balance. The game includes a library of licensed and original piano-based tracks across various genres, providing auditory cues that help with timing. Visual feedback is clear, with vibrant tile colors and satisfying hit effects. A tiered star-rating system for each level encourages replayability to perfect scores. Some user feedback suggests the difficulty can spike noticeably in later stages, which might frustrate players seeking a purely relaxed experience. Furthermore, while the core gameplay is solid, the ad-supported model can interrupt flow, though an in-app purchase removes them. For anyone seeking a rhythm title that is easy to learn but offers a genuine, reflex-testing challenge, Piano Rush presents a compelling option.
