So I've been playing on a daily basis now, about 3 hours every day. I used to be able to do streams and very fast single-tapping, and was ranking up at quite a fast pace (personally for me). But then all of a sudden, about last Saturday, I turned on osu! and suddenly the feel of the pen and the keys weren't there, and when I played my fingers (both pen and keys) were stiff. After 10 seconds of tapping with my index finger I need to change to my middle finger then the timing went all wrong. Can prolonged gameplay cause this and will resting for a few days help? Cuz I'm scared that after resting the muscle memory would weaken.
