Having played it a few hours this is a pretty good game, not exactly groundbreaking but to just come out with a full release like this is pretty refreshing.
It is a little difficult to know what you're meant to be doing at times but I would say the key thing to know that, it's not a linear game. If you can't get through an area there's a good chance you need to be somewhere else until you get something or help someone that lets you progress elsewhere.
If you find yourself ramming your head in to a wall do something else. Also explore areas a lot because it comes up saying whether not you've discovered all important or minor locations in a zone, so you might just be missing an area you need to visit. Exploring is pretty RNG sometimes you'll get nothing or just a battle but that doesn't mean you've found everything.
As for the content in the game, it's pretty okay. I wouldn't go beyond that personally, the scenes are fairly decent but the build up to them is kinda eh.
The main character has amnesia and doesn't know who she is but she seems to be totally fine just screwing everyone, which is a little weird. Some characters the only thing they do is essentially say "Wanna fuck?" and without question you can just agree to that. A bit odd.
Also through doing a quest I got a passive skill for Holly to not mind having no underwear on or being naked...but for me she was totally fine being buck naked from the start of the game...? Not sure if that's just bugged.
