This game has quickly cemented itself as one of my favorite corruption games. It's not incredibly deep, but especially as a first effort, this is a standout achievement. Big credit to Tjord for the original concept and to harold for actually bringing it to the finish line.
In terms of story, it is a basic standard war corruption plot. You play as the good guys in part 1 and play as the corrupting bad guy in part 2. The sizeable part 1 lets you get to know the characters and most are elevated beyond simple tropes, although the characters are still relatively basic. I would've liked some more setbacks in part 2 as it really feels like everything goes the protag's way, but it was still a serviceable story.
In terms of corruption, this is where the game shines in my opinion. The actual method of corruption is pretty basic, but seeing how each of the many heroines turns after becoming corrupted is amazing. There are many, many girls, and while some obviously get the spotlight more than others, there should be at least one that you will get attached to. The breadth of different personalities and designs is a big positive, as it never feels too stale or repetitive. My personal favorites were characters like Sofia, Constance, Marie, and Orlaith, who pretend to be their uncorrupted selves in order to spy on or sabotage the good side.
The other standout piece of the game for me is the attention to detail. There is post-mission dialogue for most every character in the duty roster after every mission, and while this seems small it goes a long way towards endearing you to the characters and making them feel like a cohesive army instead of random people grouped together. There's also optional corruptions, with separate scenes, one branching storyline, and one entire battle locked behind different combinations of corruptions. This helps the replay value and lets you see a different side of some characters.
The combat was basic but serviceable. I really enjoy how each battle is basically a mini puzzle - once you know how the enemy works, it's up to you to find the proper combination of skills to counter them. A few battles were more RNG heavy than I would like, but with liberal saving it's not that big of an issue.
The only bugs I encountered were in combat, with some status symbols staying on the text window even after the battle was over. Also, sometimes the battle would refuse to end even if I was defeated and I had to reload a previous save, although losing in part 2 basically just means reloading anyway. Finally, the script could use a little proofreading for spelling and grammar mistakes, although it wasn't bad enough to be terribly distracting.
All in all, I really enjoyed this game, will be replaying sections of it often, and look forward to the next game by this developer.
