Here is what i liked:
- Fantastic characterization, each character feels just nuanced enough and has thier own motives and goals 
- Spell Variety is good enough
- Simple combat that is just enough to get by without feeling bad
- Crazy amount of side content and branches
- Nel's systems are implemented well and skips a lot of painful grind
- Good story to gameplay cohesion in general 
- the ghost possession system with the puppet and everyone else is something i definitely want to see more of as i find it very interesting 
- Lena is cute, charming, and precious

Here's what i didn't like:
- Some saves cannot be saved during, i tend to crash so this lead to me having to redo some very lengthy scenes as they'd crash before i could save
- As much as i like Celica and Nel, there is a particular scene i felt like Nel just kinda stole from Celica. the Celestian transformation. Its kinda just hand wove off by Nel that its not a race but it was a really story important moment for Celica that kinda just got soured by Nel once again doing everything for her. Celica brings it up but relents far to easily. I feel like Celica should have been the one to do the transformation by herself. Especially since Nel cheering her on but then kinda just doing it for her really makes her disingenuous. which im not sure is the intention.  The parts leading up to Nel just cheating the form are fantastic. and i was about ready to call it the best part in the game till she just does it and ruins all the build up. I do feel like this part needs redone and its the worst bit of writing in the game. There should either be more friction from celica about how important the moment was to her, leading her to be more forward in the future againest Nel, or Nel should not do it for her period.
- I love the idea of the spirt system, but it is far too confusing in its current state. changing body owners or lowering influence doesnt seem to really do much at all. (if it actually does do something) There needs to be a more noticeable change or effect on things . There is also way too few talismans for how many spirits and things you have on the board. 
- Kimiko states that Celica must balance her spirit, and thats why she cant awaken celestian without Nel's help, but no matter how many combonations of talismans i tried, i can never get celestian form to awaken on Celica without Nel. Not sure if its possible and Kimiko is just poorly worded on that part, or if its possible and the spirit board is just too confusing. 
- The ui for the spirit system is very rough and clunky. I do not like that you have to press the opposite side of a spirit to get back the opposite talismans from them. it feels very counter intuitive and i constantly find myself clicking to take talismans back only to realize i have to click the suppression side to get the empower talismans back and vice versa. 
- The game has a tendency for characters to just wander off after scenes with literally no hints as to where they have gone. like Miranda (the monster hunter) It'd be nice if there was a small hint as to where they have gone so we can try and figure it out ourselves without constantly going to the fortune teller
- there is possibilities where you can get softlocked permantely by enemies if they apply enough statuses, they screw you long enough for your potions to wear off, or you have the right skills on. I feel there should be a once per battle breakout system that you get 100% chance to free yourself if Celica climaxes like 5 or 6 times to help alleviate this. 
- Relationship points take too long to grind with battles, Lena helps fix this, but lowering the amount of battles it takes would not go amiss either for people that dont want to just buy the progress. 

Stuff I hope to personally see added: 
- Bad Ends, there are several that are teased but always loosen up at the last moment. I dont know if any are planned but i'd like to see some scenarios where Celica fails her quest that requires a reload
- More involvement with faylen possession, right now shes kinda just there. You cant even get Glace to acknowledge her. 
- The Teleporting mirror Able to fuse with the hour glass, so it can change the time to go to for example the galleon without you having to wait till 12.
- Clothes fusion (i just think it'd be fun to be able to fuse outfits together and create different positives and negatives as well as different designs

All in all though, I feel like the focus on a great rpg first, then the H second was a really good call
