Oh my this game is actually extremely difficult!! It's unlike most rhythm games I've played and I love it. Sadly I only made it to 4 though (because I suck) but I'd love to see more games like this one!
We have another rhythm game! It's called A Dance of Fire and Ice: https://store.steampowered.com/app/977950/A_Dance_of_Fire_and_Ice/
And you'll see more levels of this one when we finish the full version of Rhythm Doctor! Thank you!
