The game has potential but it's already completed so wah wah, but it's not great. You are a detective solving crimes, fighting through waves of thugs, which sounds cool on paper, but the combat animations are really low quality, either you double click the movement keys to run and then hit Z to do a knee attack or you use your pistol attack which regenerates ammo once every 5s roughly.
The quest progression is kinda dumb at the end cause you need to read a guide, the event triggers are nearly impossible to find.
You can beat the entire game without getting raped, that's a great feature, the H-scenes are either defeat rape or prostitution, the animations are very basic, after you beat the game there's no gallery unlock, the scenes are nothing interesting, go drop a save if you want to.
To really make this game interesting there's a need for better more responsive combat controls, and of course much better H-scenes, take a look at guild meister 2 for a good 5/5 example.
In fact, if you haven't played guild meister 2, do yourself a favor and go play it, you won't regret it.
