Hello ! thanks for the feedback, The thing is it shouldn't be so hard because It's made in one scale , you can just play the melody side going up or down from Z to E and matching that with the backing drum track! That would be a good way to start practicing being in rhythm without worrying about ur right hand and arrow keys !
AND YES whenever i have time i will definitely work on this adding different types of game modes and whatever I could think of (or gets thrown at me as idea :D)
