Rhythm Rush! is a single-player action game built around bringing your own music into play. Add MP3, OGG, or WAV files by dragging them into a folder, then take on stages whose obstacles and enemies appear in time with each song. Its central appeal is the combination of a personal soundtrack and rhythm-driven movement, rather than a fixed track list.
The three modes put different spins on that setup. FOLLOW asks you to trace a line that shifts with the music while avoiding beat-spawned objects; DODGE focuses on evading obstacles, while FIGHT combines line-following with waves of enemies to defeat. Eight maps offer distinct looks and color-changing options, and three bosses can be unlocked. Four standard difficulty settings and a custom difficulty let players choose or shape the challenge.
Progression is tied to performance: playing songs on harder settings helps rank up faster, while stats, friend comparisons, and achievements give players ways to track improvement.
