just 3 hours?! that's incredible! great implementation of the theme; i hadn't noticed anything until i recharged for the first time and realized, ''holy shit''
remember that scene in the matrix, when neo was like, ''why do my eyes hurt?'' and morpheus said, ''you've never used them before''
it was a lot like that
also the sound design in general is spectacular, great choice on those, they make recharging and everything immensely satisfying
