About Rhythm Doctor
Rhythm Doctor challenges players to save patients by striking the spacebar precisely on the seventh beat of a heart’s rhythm. Each level teaches a distinct music‑theory concept, from polyrhythms to irregular time signatures, while weaving an overarching story about doctors and patients. The game offers solo play, local drop‑in/drop‑out co‑op, a robust level editor, and full controller support across Windows, macOS, and Linux, making it both an educational rhythm experience and a creative sandbox.
01 / THE GUIDE
Core Mechanics
Players use the spacebar to defibrillate patients, aiming to hit the exact seventh beat of the visualized heart rhythm. Timing accuracy determines whether a patient survives, turning each tap into a learning moment about rhythm. The system rewards perfect sync, while missed beats illustrate concepts like polyrhythms and hemiolas, letting players feel the theory rather than read it.
- Start each level slowly to internalize the beat before increasing speed.
- Watch the visual cue closely; it aligns with the audio rhythm.

Level Design & Rhythm Theory
Over twenty handcrafted levels each present a unique storyline and introduce a specific rhythm theory element. The designs range from simple 4/4 beats to complex irregular signatures, gradually building player knowledge. Each level’s narrative ties the musical challenge to a patient’s condition, making the theory feel purposeful and memorable.
- Pay attention to the story cues; they hint at the upcoming rhythmic pattern.
- Replay levels in ‘Night Shift’ mode for a tougher rhythm test.

Multiplayer Modes
The game supports drop‑in/drop‑out local co‑op throughout the entire campaign, allowing a second player to join at any point. Multiplayer is split‑screen, and both players must coordinate their taps to the same rhythm. Remote Play Together is available, though latency can affect timing, making local play the most reliable experience for rhythm precision.
- Use a wired connection for Remote Play to reduce latency.
- Communicate clearly with your partner about upcoming beat changes.

Level Editor
Rhythm Doctor includes a robust editor that lets players create, share, and play community‑made levels. Users can import personal music, place notes snapped to the beat, and apply over fifty visual effects and backgrounds. Created levels are accessible through Steam Workshop, expanding the game’s replayability beyond the built‑in campaign.
- Start with a simple track to learn note placement before adding effects.
- Test your level in both solo and co‑op modes to ensure balance.
