it's very nice of you and i really appreciate the offer but that said, the game i restarted goes very nicely and i'm already getting close to wave 80 straight after reincarnation so i should be where i was in the original save in couple more hours of grinding :)
i think the golden enemies help speed up the progress as you get more gold and exp and even though the modified lvl 50 is bit of the hurdle to overcome once i got past it the game sped up quite a bit
