I just started the game and got to floor 30ish and got my ass kicked by A Byakuren that shoved my shit in. Does anybody have some tips for somebody just starting out? I've been investing in the kappa jews to unlock more checkpoints but starting off at level 1 at a level 20+ floor doesn't exactly make it easier. Am I missing something here or do I have to just keep grinding items to the point until I wont be easily murdered?
