I liked the chess puzzles too, they were difficult but it was a fun brain teaser. I did have trouble with the last one though since it took me a long time to consider moving a pawn tothe other side.
Same here, I managed to work the screens out through trial and error, but didn't really know what the goal of the puzzle was until I realized you could go through her room too.
Fern having a high potential value would make sense seeing as he is one of the characters we spend the most time around. He has the same + value potential as Anna, Cain, and Victoria who we see all the time.
Currently doing a grass monotype run, Corey's crobat would sweep my entire team so I leveled up a jumpluff until it out sped and could put it to sleep. I don't think I ever would've gotten by Corey without jumpluff.
