Since there is so many elemental damage in the game it would be nice if visually its easier to tell what element each mob is, right now its mostly guesswork.
Mariah's LLM scene feels unnecessarily grindy, as it is effectively doing the same action 6 times over. Perhaps make it only around 4 times in total (so you only have to do 2 extra if you took both opportunities to spy on her). I do realize this is also to give a better chance for players to have a higher intimacy level with mariah so the scene has lower chance of failing.
Another thing about mariah is when she jacks you off on your bed, the game evaluates your intimacy. I got the lowest rating and it didnt make the most amount of sense as i always maxed out the intamacy points availble through talking. My guess is it's because i did not give her the moonlight rose (i found it later on) but that still doesn't make sense to get the lowest score even though every single other thing was maxed out.
Jakku's balance seems to be a little off? Initially the balance is alright, casual being easier than nightmare, but later on (i dont know when it changes) he summons harder mobs now, and i find nightmare to be significantly mroe consistent than casual. You can easily get screwed over in casual if the 2 mobs both use hi void, dealing over 350 an attack per, or get inflicted with toxic frigid and more, while in nightmare you can do double tension divider to focus one down, and then use attack and tank through the second one significantly more consistently.
Ways to change controls will be nice,
These are smaller "annoyances" that i found: (i might update this if i find more)
Entrance to the goddess shrine plays an annoyingly long animation that doesn't need to be played for more than one time
CG gallery takes forever to load
Would be nice to be able to see the emma pictures and the claire pictures
Mouse controls doesnt work with agility trial
There doesnt seem to be a way to properly get the sparkling boom
Memory lane is a little painful to use in the sense that you haev to check each crystal to see which scene its referring to. Would be nice if it could also be changed to be sorted by character etc.
Jump + mouse doesnt have the best interaction, and there are areas where if you use mouse you can never jump in the correct direction. First occurance is when bastet & co. chases after a mouse and there is one extra section where you have to jump over a junk to get to a red chest. The return is impossible on mouse only.
AP probably needs some extra use? I have like 700 excess of them. Could perhaps be used to speed up skill mastery/exchanged for xp?
CP feels like an artificial way to bloat playtime, it isn't much as a "cost" but it sure as hell is annoying when you want to level skills. I usually just open up youtube to pass time.
All in all a really fun game to play, those are just my feedback for improvements. Hot scenes, and in general the game feels great to play with an alright plot.
