Probably going to keep this review short since it's really hard to find anything negative to say about this quest lol. This quest was a blast to play through and I loved every bit of it. This was also a huge step up from Hitodama in terms of gameplay, story and design. I managed to get 100% in the main game and I'm very thankful the seeker upgrades existed, or else I would've been wondering around for ages. Each area is really unique in their own way with their own cool gimmicks and ideas. I also love how the labyrinth connects up together, with shortcuts and alternate paths everywhere, giving the quest a real metroidvania feel. The soundtrack in each area was really nice to listen to as well, and they all fit their areas nicely.
I also loved the new spells included, and they definitely were used a lot more equally this time unlike in Hitodama. Though I still found myself using some spells more than others (especially Thunder, that's my favourite one), but it's nice how you can use spells for both combat and puzzle solving. That perfect mix is fantastic. The difficulty was pretty spot on, except for the Rose Garden area where I feel like it was a little too hectic for me with the hidden spikes and all the enemies everywhere, but other than that, nothing felt too hard or too easy. While I only done one playthrough as Rhone, the story was very interesting. It felt quite simple but really effective, and that random plot twist near the end with Naiya got me good
I might decide to do more playthroughs of this in the future, but I think one was draining enough for me for now and I've been meaning to try other quests so I'll come back to this another time.
Besides the one small complaint about difficulty in one area, I can't think of anything negative to say, so good job making a truly fantastic quest. Easy 5/5 from me and I'll be sure to try out the post-game stuff eventually too as well as playthroughs with different characters.
