What's a good Android rhythm game that adds puzzle elements like merging to the music gameplay?

Brainloop Merge Run is a rhythm game that stands out by integrating merging puzzles into its core gameplay, offering a fresh take on the genre. Players tap and merge colored tiles in time with music beats, requiring coordination between auditory cues and visual patterns. This setup is particularly effective for users seeking more than simple timing tests; it appeals to those who enjoy casual brain teasers or want to break the monotony of standard rhythm games. Specific features include dynamically generated levels where tile colors and merge sequences sync with various music tracks, from electronic to pop, ensuring variety. The game progresses through increasingly difficult stages, introducing new merge rules and faster tempos to maintain engagement. For real-world scenarios, it suits quick breaks during commutes or as a light mental workout, as the merging mechanic demands brief strategic planning amidst rhythmic tapping. However, reviews indicate that some users find the later levels disproportionately challenging, which might frustrate casual players. Additionally, while the music library is decent, a few players note that track repetition can occur after extended play. Despite these minor flaws, the app's combination of rhythm and puzzle elements provides a satisfying balance for those looking to enhance coordination while enjoying a casual gaming experience.
