You NEED to play Rhythm Doctor if you're a fan of rhythm games--especially Rhythm Heaven. The game does so, so much with just one button; it introduces various different cues, combining and expanding upon them in really cool ways from one level to the next. On top of that, there's a genuinely great story that works hand-in-hand with the gameplay; nothing super complex or groundbreaking, but the patients and staff of Middlesea Hospital are quite a compelling cast of characters. The game's still in Early Access as of now, but for my money, it's already one of the all-time greats of the rhythm game genre--and I'm certain it'll be even better once it's complete.

also i absolutely LOVE IT whenever the game does that. no spoilers, iykyk

Super unique Rhythm game - it has a progression somewhat similar to Rhythm Heaven with these short stages that introduce new mechanics, but what makes it special is that each of these mechanics continuously roll over into the next.

In Rhythm Heaven, each game is disconnected and focuses on one rhythmic pattern before eventually mashing everything together in a Remix at the end - this game takes the super unique approach of making each level feel like an expansion of the last, and has a properly great feeling progression!

The soundtrack is spectacular and the game is always doing so much to exceed expectations - establishing rules and then remixing them within themselves once you think you have a hang of them. Consistently engaging and dynamic for each stage, and has a high skill ceiling with harder versions of each stage to try and perfect.

Great little early access game and I'm excited to see where it goes next! It's already so polished and full feeling!

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!
