Small request here, any chance the location of the backpack could be moved? After too many hours in this game, I'm used to glancing at the bottom bar to see what my two skills are, and the backpack location keeps throwing me off. I see the rightmost icon, look one to the left and see a skill. So I press L2 to use that skill, because my brain says 'it's one away from the end, it must be the L2 skill!' and then I end up accidentally blowing up my mushroom pal instead of popping tonic or whatever. This has managed to end my run a few times.

While we're here, please revert the sound changes on nerves of steel. The vague little whoosh noise is not nearly as satisfying as the old meaty thwack you got with a crit shot. (Also numerically it feels pretty weak now)
