Dark Bramble... what is there to say about this place. If I got enough sleep to have dreams, I'm sure I'd still be having nightmares lol. I actually visited everywhere else first, so by the time I found the anglerfish, I knew what to do. They are still terrifying, though.
SPOILERS IN THE NEXT PARAGRAPH.
I loved navigating this place though, finding feldspar was one of my smarter moments, and he's so cool. Honestly, if it weren't for some unfortunate fish related complications in my attempts to reach the ending, it might be one of my favourite planets.
