Before I start this review proper: I played all major titles by this dev(Loren, Seasons of the Wolf, Planet Stronghold 2 and CD, Cursed Lands etc) as well as most of their older stuff. I also don't like the "gameplay part" of their VNs, so I usually play in Visual Novel Mode if I can.
Ngl I played this with low expectations and after finishing a single route, I don't feel like playing another route or different MC. But the game did manage to keep my attention. This title is yet another "underwhelming" game by WW, for better or worse.
Not much to say about the story of this game: I felt like it was more focused on character interactions with MC. Not a bad way to structure a VN, but it also puts a lot more pressure on character writing. And characters in this game will either make it or break it for you(unless you only came for gameplay). They're all simplistic, but do have their appeal if you like their archetype. And there are lots of options this time around, unlike majority of WW games Curse of Mantras has no gender restrictions!
However, there's the whole Chaos/Order alignment point system, which locks you out of romancing characters of opposing alignment. I don't like this system at all. Not only choices felt binary af, they also felt very stereotypical and boring. If you want Chaos, just be like Seto Kaiba and say "screw the rules!" to everybody, and for Order it's another way around. I'd rather just pick my alignment at the start of the game, thanks.
Speaking of romance, it works if you like flirting and implied sex. But it fails at the romance development. The majority of the characters like MC from the get-go and want to bang them after a few convos. I romanced Ash as M!MC and didn't feel any investment. They met, talked and banged. Okay. This game really should've been 18+.
I have a hard time talking about art here: I like the style, but I'm mixed on the designs. Maybe it's just me, but none of the male characters have as many thoughts put into them compared to female characters, I especially dislike M!MC designs: all of his variations look like fashion disasters. And his Order design even has an optional fedora hat. I hope it's just dev having a laugh. Another pet peeve: some male characters "sexy" designs are just them without an extra shirt on...wut?
Music is okay, sound effects are fine too. Typical WW stuff.
UI is boring, but serviceable.
In conclusion, if you like WW or played their other game, try this one. Maybe you'll like it. Or maybe try playing it with a card game gameplay.
If you like games without gender restrictions on romance options, maybe give it a shot.
Otherwise, I don't feel like I can recommend this to many people.
