A soulful little indie rhythm game made in Hong Kong where you play as a remote-cardiologist who needs to tap the spacebar on the 7th beat* (usually, there are some other types of patterns that you press after one beat, or need to hold the spacebar down for) in order to solve the heart issues of the patients of an underfunded hospital. The game plays around with it's visuals in cool/novel ways and has a multitude of banger tunes (Intimate and Lounge are my favs); Rhythm Doctor gets my full recommendation for rhythm game fans, and its simple premise make it a great time for novice rhythm gamers, too.
(Also, this game has an active custom level scene, and some of their creations are just plain awesome - https://youtu.be/VhC_8I3vWV8)
