I made it all the way to the Core fight when I realized that since I already have the 0.8 Booster that I can't save Curly and get the best ending. ._.; So, what I'm going to do is start a new game on a seperate file and do it right this time so I can get the best ending on my first playthrough. Before I do that, would anyone be so kind as to provide a spoiler-free list of what I need to do (and what I should NOT do) so I can get the best ending?
I only made it up to the Core fight, so I know everything up until there, and I know that I have to not get the 0.8 Booster in order to get a Tow Rope for Curly. Thanks for helping! <3
Oh my god, a girl on the internet. What is this world coming to?
Honestly, once you've done that, the rest is obvious enough.
To sum things up: - Not long after the Core fight, in the cabin, drain water from Curly then take her with you - Meet Curly again later on, then get her the mushroom from the graveyard - Talk to Curly until she gives you an item
