NEW GAME++

Hi Guy's & Gal's,

Just playing through my 3rd playthrough. Did the 1st playthrough on Easy and thought pretty easy. So started NewGame+ on Hard level and find leveling up near impossible as, if you die you lose your accumulated skill points and have to start again when you respawn. I think I leveled up 4 or 5 times in the whole playthrough. How the hell are you supposed to get to level 250 to open the other skill point boosts or even 350 is beyond me ? Unless you play on Normal level when you start NewGame+ ? Then you would probably need to play through NewGame plus 20 times to get to level 250 ! Has anyone got to level 250 or even 350 ? And is it worth the slog and effort ?
