Still in early access as I write this, but Rhythm Doctor is a very charming little game that is definitely worth checking out. The pixel art style is cute and gives the game this really cozy feel, which I appreciate. The characters are endearing, and though this game doesn't really have much of a story (yet!!), they were a highlight of the experience.
As for the actual game, Rhythm Doctor takes inspiration from Rhythm Heaven, and is a one-key rhythm game. On every 7th note, you click the space bar. What comes then are a plethora of different heartbeats, keeping you on your toes. Some patients only have 2 beats instead of 7. Others use a swing rhythm. Others need you to hold their beat down. There are even some wholly unique ones that comes with certain special stages. Rhythm Doctor manages to keep the gameplay from getting stale, while still making sure the core gameplay loop is still simple and fun. This all comes together for the boss stages, with very unique gimmicks and interesting shifts in gameplay. I would like to especially highlight 2-X. I'm not gonna spoil anything, and you definitely shouldn't spoil yourself either, but that stage really impressed me.
The music is obviously well done. There's a decent variety of songs to be enjoyed here, from slow lo-fi to fast-paced electronic. The night levels especially have some really good songs, with Rollerdisco Rumble and Bomb-Sniffing Pomeranian being my favorites.
The game is pretty short and sweet (so far!!), but there is official support for custom stages. The community's still pretty small, but they've been hard at work making unique tracks and levels, and they're only gonna make more as the game grows.
Very underrated fun time. Go give this game a try, and give it some support. I can't wait to see this game grow!
