Heya fizzd! Loving Rhythm Doctor. It show that you don't need to change the formula of how games are made, just some of the variables. Simple, fun, ties the story (Even if there is only a little of it.) with the gameplay and it's at the "You can't blame the game for your slips because of how well it was put together" level of difficulty. Love those kinds of games. I'm still playing the same stages for the great music. Either way, I was thinking of some boss ideas (Like how the first boss plays notes off beat) if you liked to listen in. Again, keep going at the work.
