As I write this review, I have a lot of thoughts rolling through my head. I've beaten the game twice, one on the good route, once on the corruption, and I feel very conflicted on this game. On one hand, I like the art and the characters are very endearing and likeable. On the other, the poor art shows up at the worst moments and can take you out of the experience. On the other hand, there are some factors that make this game so bad, I'd struggle to recommend it. Here it is.
Part 1: After getting hit by a car, you're gifted a magic penis from a demon in order to corrupt the women around you. Why? Because she needs you to be strong enough (thanks to the sex) to rescue her and dominate the demon world. Along the way, you corrupt/arouse everyone around you in order to get stronger. The women you get are your Mom, Sister, her friend, your bullies' moms, your Nurse, two random milf, a Mechanic, and the woman aiding you with your misssion, Nelea. The individual stories are alright, though I have some minor issues (the player is a dick to Amanda, when you'd more expect the corrupt thing to do would be to use her to get closer to her mom/ preparing her to also get boned), but the major plot mostly stops after that. The End of the game has you beat the demon that took over the Other World. And you can either allow Nelea, the demoness, or you rule over the land. Obviously, you taking over is the best ending.
Part 2: Gameplay
The gameplay is a basic game of running around to meet people, then increase their lust/corruption to get more scenes to level them up to repeat the process. There are some issues, as there are several bugs that make this difficult (An error message instead of a hint appearing, the game saying you can do something when you still can't [Saying you can chat with someone, when you still need to gain points by talking to them], saying you need to do things that you don't actually need to [Waiting to make Lisa, desperate for your cock, when really you just need to talk to her until you see all her dialogue) and also, there are some scenes even for early on in some character progression that are difficult to trigger (such as some characters only having scenes occur on a single point on a single day, so if you miss it, you now have to wait an entire week to progress them. While that does mean you can focus on others, if they're one of the few remaining ones that can be irritating. Your walk speed, while fine at first, can be too slow in larger sections (Park, Otherworld). Also, you get spells from exploring the Otherworld, but they suck. Invisibility is only used a few times in the overworld, and the X-ray vision is used to either see underwear/nude girls whenever, and ONCE to see some enemies. There's quite a few puzzles, and for the most part, their fine. They aren't overly complex, but they do tickle the brain slightly, so I appreciate them.
During the end game, you're forced to stealth through a castle, and it's the farthest thing from fun. Their sightlines are abysmal, as I've stood in them and not been seen, and been outside their sightlines and been caught. Plus, being seen immediately boots you out of the Other world, forcing you to either quickly exit and reload an autosave, or wait till night to try again. It sucks, same with the final boss fights (which I won't spoil)
Part 3: Art
The individual character art is fine, and even nice looking. However, whenever it transitions to the sex scenes, a poor looking gif appears that does NOT match up with the quality of the stills. And considering that those are the scenes you'll be searching for and want, that's extremely disappointing. Also there are two random movies used for two random points. It looks better than the gifs, but not the stills. Also... why? Why not have 1 for each character and for major moments like the first time you have vaginal sex?
Bugs: Oh my god there are so many bugs. Text errors, errors when changing time, lag during the endgame, multiple crashes for next to no reason, missing animations, missing art, characters not appearing when they should, characters being places on days they shouldn't, menus resetting you after you go back a screen, god there are so many bugs.
This game is kind of a mess. If you want to try this game, only do so if you understand that this game has several bugs, the game is very grindy, and that the art isn't always as good as it looks on the box. If you can look past that, it can be enjoyable... but for your own sake, choose Lust or Corruption and beating that route. Beating both is tedious and not worth it.
