Thank you for feedback! I chose F and J because you can easly find them on keyboard without looking (most of keyboards have those little bumps on those keys). And I find it easier and more precise to use both hands to controll movement in this case. But yea the more I play the more I hate the music I made. It's super repetitive but better something like that than nothing. Well the 'sound design ' is defenitely the thing I have to improve :D
