A very fun to play ARPG that combined with some danmaku battle mechanics
Relatively casual imo and definitely not hardcore

Things I like:
Game battle is smooth.
The graphics is good for a game that originally released in 2014 on ps4.
The soundtrack made by Hachimitsu-Lemon is great.
Spell cards can be collected to unlock new skills.
The plot is silly in a good way.

Things I don't like:
Manual save is only available between chapters and autosave is weird.
The quit game button is literally F4 which for me this design is quite odd.

Btw:
I love my queen Remi.

This is the weirdest Ys game I've ever played. There's not even Adol, just some little girl and some chick with knives that isn't Karna.

... All joking aside, this is a serviceable ARPG with 2hus in it. A bit basic and rough around the edges, but if you enjoy either of these things, you'll probably enjoy this.

Now, rough around the edges, I say? Why yes. The platforming as Sakuya, frankly, sucks. Remilia has the ability to slow the descent of her jumps, allowing for more precise landings, but Sakuya does not. Often, I'd find myself either overshooting a jump or just landing on an edge, only to slip off. There's also knock back from enemies, meaning that you can land a jump, then get hit and fall off anyway. This even happens in areas with narrow paths that you can fall off. Now, the real annoyance of this, other than having to redo things, is that you lose money. Granted, money isn't that important until end game, and by then you can get lots, but it's still annoying to go broke because there's a jump or five that just suck because you picked the wrong character.

Remilia and Sakuya, sadly enough, share a lot of the same equipment. Weapons are unique, but they can, will, and do, share a large number of armors and accessories, though each one does have some uniques. The issue with gear is that they're all random, stats wise. There's little rhyme or reason as to what item has what stats, and you can run across items that totally tank most, only to have massive HP boosts, or attack, or any other stat.

Granted, it's perhaps better than just having an objectively best piece of gear, but it's a bit troublesome if you want to have at least decent stats in everything. And again, because it's random, it could mean you will grind for hours just to find something decent. You could go whole maps finding nothing but trash, or waste all of your money from end game boss grinding on buying stuff that is objectively worse in every way.

This is why the end game item dispenser is a gacha machine, because it's all a gamble. And at 40,000 a pop, it's a big gamble.

So what's actually good? The music, of course; this is a 2hu fan game, after all. The combat is also good for what it is, with each character having a decent number of skills with which to use, though the spell card selection is pretty slim. However, you do not level these skills, instead you just earn them via leveling... and, well, it can lead to some skills just being objectively useless as time goes on. Especially with Remilia, as some of her newer skills are just straight upgrades to previous skills.

The plot... well, it's a 2hu game. Especially since the Scarlet Devil Mansion gets destroyed, so it's totally legit. It's not that super deep or compelling, but it would fit in pretty well with the franchise as a whole, and it's very low stakes (Gensokyo isn't really in danger, there's no Lunarian plots, Yukari isn't fooling around), but still enjoyable.

This game has a level 99 cap. You do not actually need to go this high, but you can. It involves a lot of secret boss grinding... and you will come to hate her track, even if it's actually good. I've heard some people claim that Remilia is stronger than Sakuya, but if anything, I think it's the other way around. Sakuya, outside of the terrible platforming, feels like easy mode, especially when she gets her final skill. It shreds the secret boss pretty easily, and only gets easier with more levels. Remilia, on the other hand, I found has a harder time with bosses, and her final skill isn't nearly as good as Sakuya's. But she does have the better spell cards, so...

But if you want even harder mode, just turn on bullet hell. Then cry.

So yeah, this game is pretty good and you should get it if you enjoy ARPGs and 2hu.
