Hello! I am enjoying this game a lot so far, but there are some things that should be improved. It would be neat to add the option to have the notes labeled as intervals (and key selection). Also later on, maybe the ability to choose the type of notes in the sequence, like a pentatonic scale or different modes (Mixolydian, Dorian, etc...). Adding things like this will change your game from a fun pitch memorizer to a legitimate musical tool.
