Shame it hasn't gotten any updates. More poses/girls would have done wonders for replayability. Still one of the best adult games ever though.
First off, for any 3d walking game I recommend downloading software that lets them rebind mouse inputs (if you don't have drivers that let you do that natively).
Here are the most important ones for this game:
w - walk
shift - sprint
ctrl - crouch
f - interact
tab - phone
These would work on any mouse but if you have extra buttons it's nice to bind one to another mouse mode where everything is set to default so you can easily switch between menu/walking and interaction mode. Btw this same layout works for most 3d games with a few tweaks.
As for the game itself:
Girl design: 10/10
Personal bias but she's cute, she's got well sized titties, beautiful nipples, nice bubbly butt and very nice expressions. You can customize her underwear but personally there were only a few I liked. No other customization.
Gameplay: 9/10
The time stop is perfect, haven't seen any game do it as well as this one.
The groping isn't bad but it could be better, lacks a bit of responsiveness but as long as you go slow it feels fine.
The interactions are nice, really feels like you're a creep completely ruining a regular girl's day.
The cum mechanics are nice. You don't have complete control but it covers enough to be satisfying and the girl actually reacts to it.
The other powers are alright, hypnosis is definitely useful and climax is very efficient for progressing. The other ones I didn't find as useful. If you could fuck other girls then the nudity power would be great but as it is it's kinda just there, at least it's cheap. It's also a shame you can't combine it with other powers.
The succubus I didn't find all that interesting. It's nice to look at all the scenes once but coming back for more felt unnecessary as it basically just feels like a scene viewer.
Going to her house is a nice touch because it adds to the creep vibe and feels more immersive but it lacks some actual substance. Not bad but could have had more to it. Maybe breaking into her house at night and assaulting her in her sleep after knocking her out or something along those lines.
The sex locations (both in house after getting comfortable with her and outside in certain spots) are similar to the succubus, just felt like watching a scene viewer, didn't feel the need to do it again and might be one of the biggest missed opportunities. The organic sex felt nice but lacked variety, while the posed locations were varied but lacked control. If those scenes (even if there were fewer of them) just had piston mechanics that would already have made them better.
Free mode is fine if you just want to see what the game has to offer (though if you've read my long ass post you probably know most of those things already) but I wouldn't recommend using it for more than that since it really just breaks the tension and immersion. Something like being constantly detected by random girls to unlocking the ninja perk and never getting seen really adds to the experience. It feels as if you're stripping the girl of her last line of defense over time and you just don't get that from free mode.
Progression: 7/10
Lowest score but also the lowest weight on the overall rating. It's a bit annoying to get to the high value perks but I guess it also added to the tension. The way I went for the highest value perk was by picking up collectibles which always respawn in the same location and yield a decent amount of score if you don't mess up. I later realized a more effective way would have been to get the climax skill first because then it's very easy to raise affection for the girl using that and with a high enough affection you can just ask for sex and go for as many points as you want. I wasn't a very big fan of the game post that point though since I liked the game more as a molestation game. However, being able to corrupt her on any particular day is pretty nice and for that I recommend using cheat engine and finding the values for her affection and lewdness and setting them to 0 every day. That way you can enjoy the mind break every time and watch her go from being scared to being lewd af.
Overall one of the best adult games overall and certainly the best time stop game. I do keep coming back to it so I would say the replayability is there.
