Overall a very good game which had potential to be one of the greats, but fell just short. Took me 8.5 hours to get 2 out of 3 endings.
Firstly, the character art and design is exceptional and extremely high quality. The scenes are incredible to watch and it is great. The voice acting also adds an extra depth to the scenes and gameplay, making it very enjoyable to play. The scenes also have a bit of animation which is always appreciated. Obtaining the scenes is a bit of an issue, you do have to lose the boss battles in order to unlock the loss scenes which is a bit of an annoying waste of time to be honest. I didn't lose the first boss battle (i beat it on my first dungeon attempt) and I didn't realise I had to lose to see the scene. I still can't see the scene as there is no button to fully unlock the gallery post-game. I do appreciate that there is a gallery and CG viewer though. Anyway, I started losing all the boss battles on my first attempt to see the scenes, but then I didnt get any scene for the succubus dungeon - that one you actually just have to win, so again, another waste of time that the game didnt explain. I wish the game had a way to see the scene if you win the fight (e.g. a reminiscence memory to see what wouldve happened if you lost the fight), that would improve the game alot. The character is also really nice to intereact with. Una is a great, cute girl and made the game much more enjoyable.
The gameplay is the main reason why I tried this game. This is my first card/deck-building H-game and I am certainly impressed, I defeinitely enjoyed the combat aspect. My only issue is that the deck building gets extremely complex after the first few dungeons. There are so many runes and card combinations. I tried to build everything by myself but i kept failing on one fo the dungeons so I just used a walkthrough guide which kinda made the game less fun.
The story is where the biggest issue arises. I don't like the fact that once you beat the final boss, youre already locked in an ending, I thought that I would have the choice to make at the final artifact. Instead, the ending is decided by 2 conversations in the middle of the game. On my first run I got the neutral ending which is garbage, you dont get any scene. On NG+ there is a button to change your choices and I then got the happy ending. I do like taht the scene is a wedding scene, but I think this game design to make the story like this is awful.This is the part that turns this game from an A+ tier game to an A tier game.
Overall, this game is very good and extremely well-polished with great art and scenes and gameplay. The main issue is that the endings are not determined after the final fight, but randomly in the middle of the game. Still, this game is an A tier game and I would definitely recommend it.
