So, i've been playing stepmania-like games (pretty much only 4 keys) for almost a year now, and i've always have been playing like this: one finger from the left hand for the last tile, and three from the right hand for all the tiles left. I've never had any problem with this until recently, where i've been quite bothered with some stuff, like the fact that i have way more difficulty with holding notes (specially the middle right note), and that i run out of stamina really quick, not to mention the lack of space i have, since i play on a notebook and my fingers are quite big. Could it be that i'm only being paranoic about it or it troly is worse than playing with tho fingers for both hands?
