Rhythm Doctor is a good rhythm game. My only real complaint is that it's short. I would have liked more levels that gradually increased the complexity of newly introduced mechanics. You get a short tutorial and then it's straight into the frying pan! And some mechanics are only in a single level!
Other than that though... Loved it. Great game. I get the songs stuck in my head a lot!
Oh yeah I know that. I meant as a progression sort of thing. There's little ramp up to new mechanics most of the time. Sometimes there's tutorials for new mechanics on the boss levels!
But like I said, I still love the game. It's just something I noticed.
