This game is a 5/5 if you like one of these things: Steampunk, the Detective genre, flat chested girls
Otherwise, I suppose it's a 4/5, it's still worth playing but it's not going to rock your world.
I completed this game in about 15-20 hours. The game is about Sophie, a cocky new detective trying to make a name for herself. Interestingly, it's not some drug or something lame forcing her into depravity, it's entirely her own motivation into being a pervert or not (obviously you should make her perv out in at least one playthrough). Also, there's a New Game+ mode where you carry over your corruption, meaning you can experience all the events from a new perspective. If your first run is a virgin run, you can effectively play the game a total of 3 times (virgin, corruption, turbo slut).
GANG ROUTE
The game is split into two sections and one is the gang route, which is really poor and weak. It was definitely added to pad out the game with filler. The gang route involves the most basic RPGM gameplay of attack-heal-attack while waiting for lengthy enemy animations from the same 2 enemy types over and over. Do yourself a favor and constantly get upgrades to get through this grind fest faster. H content mainly consists of losing to enemies, which is impossible as Sophie is able to heal 20 bullet wounds with first aid, infinitely, 50+ times a dungeon run. The one saving grace is that exploring the dungeons is fun and does use the steam punk theme.
DETECTIVE ROUTE
This is where the game makes up for it's below mediocre gang route. You will actually get to solve a variety of crimes, many with an H event angle or a steam punk angle. The gameplay here is great and not something you would see in any other game. The detective route is so good, it bumps the game up to a 4/5 on average or a 5/5 if this genre is your jam.
If you're a developer, definitely take this game for inspiration and give us more interesting games about steam punk or detectives!
