lol i'm sorryヽ(゜～゜o)ノ
i know i'm probably just weird for having this control preference/blindspot in my dexterity coordination... but i really cannot use WASD + Jump on my left hand if i'm using my right hand for another action (the J key for attack). I can't use my right hand to Spacebar + J either xD
So basically what i might have been able to handle is J/K + WASD/Arrows, or Z/X and Arrows i've seen in a lot of games.
