Gorgeous game! Pixel art and music were phenomenal. Unfortunately I am as musically challenged in games as I am in real life.
Tutorial I felt threw me to the deep end from the get go so would be nice to have some sort of difficulty settings but completely understand if that goes against the intentions!
I do think the note layout may benefit from being fixed at the cost of not matching the notes? AKA more guitar hero like where the keys come up in the same place.
