You are maybe the fifth person to mention the octaves, haha. At the moment, I'm starting to think something like:
Easy mode: we give you the octave guardrails
Normal, hard: you have to select the right octave and the right note; if it's the right note but wrong octave, the tile turns pale green. Also, maybe some new design for the grid so that you can toggle the octave up or down beside the superscript of each tile
