For the price, it's a bad otome game. You might enjoy this, but I think if you do, it's largely because you haven't played a better otome game yet. Which is fine, but this isn't the game I'd throw my money at the genre with first.
I 100%'d it in 5 hours, with about 30 minutes of that afk, and I am a faster reader, but it is very short. There's about 4 endings, all of which lock during 1 prominent choice at different points in the same route, and there's not much of a relationship meter like in the first Demonheart game (so dialogue often repeats with not much variance on route). There's not many CGs and the quality varies between them quite a lot (for example, Esmius's was miles better than Nissa's). The UI design is also a little clunkier than most otome games, and the skip function is tedious. And they ditched the personality system that I enjoyed in the first one (but they are bringing it back).
As for the story, which is the main thing people come to this series for, it was decidedly mid. I enjoyed the universe and the concept of witches trying to obtain demon flesh with the unwilling help of a demonspawn slave, but truthfully I could have enjoyed the most trash premise and terrible execution purely because I love this world and lore. The stories fall flat and a lot of interesting threads are barely touched on, and where I would be tricked and surprised at plot twists in Demonheart, this felt very standard. Which arguably, isn't a bad thing - but it's not the quality I've come to expect from this studio. Purely because they've done better.
The characters motives and feelings also got explained to us less, so I couldn't really connect with this the same way. In particular, I really hated this player-character and felt she was so much less than Bright in every way, as I often found myself going "I would pick none of these options" and then cringing at her.
It felt much shorter for the same price and felt like the content overall was way lower quality.
Maybe take this with a pinch of salt, as I've only played this after hearing about the patch to add some content about this game into the Demonheart: Hunters game, and wanted to understand it first.
I'll likely play the Cursed Trial when it's complete, because I am a simp and it looks much more like the other Demonheart game. But alas, I'm not the target market to buy this game, nor did I go "oooh, a blue dude" and buy it on launch.
Final thoughts: get it when it's on sale, otherwise skip it and go to that instead. Unless you're really desperate for more Demonheart content, or new to the genre with a lot of money to waste.
Edit: For anybody wishing to start the demonheart games, this could be considered a prologue to the first game.
