This game is extremely hit or miss. It's either the best thing in the world, or the worst thing in the world, no in-betweens. It has some incredibly good parts, and it has some ragequit-inducing parts.
The very bad:
1. The intro. My fucking god, the intro. I only made it through the intro on my third try. It's long, it's a massive infodump about things you'll never wanna hear of again, and it's so. damn. boring. Like it's at least 100 screens. Pro tip if you're picking up this game - set up a timer for 15 minutes or so, and force yourselves to sit through the intro until the timer rings. By that time you'll be at least a little bit invested in the story and won't wanna ragequit as badly. This game is like Fallout 3, would be incredible with a skip intro mod.
2. The tone. The game has a tonal dissonance - it tries to be too many things at once. In particular it tries to be both a comedy and a thriller. That kind of just doesn't work too well - you have one part of the game that is all about creating tension, and another that is all about relieving tension, and in the end instead of an overall structure of the story you have a rollercoaster. Both a comedy and a thriller would have been fine, but you gotta pick one and discard the other, can't keep both - too many a scene have been ruined by either building too much tension where there really shouldn't have been any, or by ruining the scenes which should have had a lot of tension.
I can see definite influences of British comedies like Hot Fuzz here, but if we take Hot Fuzz as an example, it doesn't like, actually build tension all that much. Its antagonists are all laughable, their goal is a joke, and their methods are more funny than anything. Hot Fuzz doesn't build too much tension, whereas this game kinda does.
The either very good or very bad:
1. The jokes. My or my, the jokes. A few of them hit really well. Some are funny jokes, but used a few dozen times too often to still be funny. Too many of them fall flat on their face from the start. An unforgivable amount of them uses the "Any reference is a joke, and they must be pointed out" sort of joke - at least, unlike some games, it doesn't highlight them in cursive so that you know that this is a reference and you must laugh.
2. The story. The synopsis is a tired old "ancient conspiracy is trying to dominate the world, and only this unassuming teenager with no discernible qualities can possibly save it", but hey I'm not complaining. Sometimes the story works surprisingly well, quite a few times actually, which is more than what can be said for most naughty games. And sometimes, the story shits the bed, some sort of divine intervention happens, and MC and his crew is allowed to essentially bypass/dodge a problem.
I gotta give the story credit though - it doesn't make MC a total dick and make him abuse his power too hard (leaving it to player's choice to abuse it), and it doesn't make him a total cuck and take away any agency he might need in order to proceed in the story - he does have agency and feels like a character, not a puppet.
On that note, the consistently good:
1. Characters. They feel surprisingly deep and refreshing, despite being pretty archetypal - keeping their number relatively low, and letting us spend time with them, allows them to flower. Their dialogue feels great (at least after the damn intro), and their personalities make them easy to attach to and like. Consistently good.
Which feeds into...
2. Sex, the part we're all here for. Consistently great. Even the tamest scenes, great. Even the cockblock scenes, great. All girls are attractive (even if a little too conventionally attractive, without too much variance between their bodies), all of the renders and motions are great, all of the situations are hot, and their personalities existing make all the scenes even hotter - because you actually care about the girls. Definitely worth a few wanks.
Overall verdict: do try this game. It's alright, if you soldier through the damn intro, definitely worth a download, and I will be keeping an eye on how it progresses.
