That was enjoyable. Kinda reminded me of some RAGS games, in a way. Kinda a classic porn game feel ^^
There was a bit too much trigger search, especially towards the end. Some can be quite obscure. It doesn't help that a lot of subplots seem to be interdependent, ie you can't do them before something else so even if you checked location X at time Y it might not trigger until you've done some seemingly unrelated other things ... plus, some stuff felt a bit red-herring-ish, like the basement room, or (early on) Rain.
The walkthrough I needed for
Otherwise I thought the walkthrough was incredibly useless as unless you follow it exactly it won't be helping you figure out what event is connected to what; not even which time or anything ^^; It's more a "solution" than "walkthrough", I'd say.
Characters ... overall nice. Sometimes it felt a bit "porn generic", oh, yeah, sure, you nice random person dude, help me take pictures. And clothes. How about a blowjob in exchange? That sort of thing. But, eh. It's about expected
Writing was okay. Often a bit rushed. A few mistakes here or there; in a scene Lara for example is twice referred to as "he" ^^; Bit of a tendency towards run-on sentences but just this side of still being ok.
Ultimately it took me just shy of 100 ingame days to solve. Don't know if you got a next project planned or something, but imo some repeating events would have helped with the grind. There was a lot of "we can do that again" but then if the path is done it's just done and you can't interact with characters anymore; or at least not that I found out.
Anyway. Onto the 2nd chapter ...
