Isn't it an amazing feeling when you go to a concert and the drum beat matches your heart beat? Music has been shown to have restorative powers, and that concept is taken to the extreme in Rhythm Doctor, a one-button game in which you rely on the power of rhythm to save lives.
Rhythm Doctor puts you, a trainee doctor, into the emergency room with a room full of sick and dying patients. In order to save the lives of your 8-bit patients, you need to watch their ECG and hit the spacebar on the seventh beat. The funky background music gives you the tempo and keeps you on track. You start nice and easy with one patient and one heartbeat, but don't get cocky - things quickly get complicated when multiple patients present at the same time, and their heartbeats are all on different rhythms.
