Well now after having played through from start to finish of 15b in two sessions, overall, its still above average. Some obvious missteps in this last update, just hastily launched without even basic testing, to be fair.
Isa's storyline has always revolved around this ex-boyfriend, boyfriend, ex-boyfriend with memory and continuity issues. In the first mention he's the ex that has his calls blocked and resorts to e-mail to try to communicate. Later Isa appears to be texting/e-mailing and referring to him as her bf, not ex. Connor "accidentally" advises her to give the bf another chance. Also, some point early, she has a creeper outside her window, and Connor promises to protect her in the future, even suggesting using the lamp as a weapon (disappears in later renders hehe). Connor gets a late night call from Isa, whom needs to be picked up off the street, seemingly in a bit of distress (obligatory cup her pussy moment

). We later come to find out that she had been cornered in the bf's place, held against her will (kidnapped) and she had to crawl out of a bathroom window in order to escape. The writing's clearly on the wall pretty early, but it all seems to be forgotten.
This could have been an opportunity to increase the home's security like motion-sensing floodlights, alarm, etc but whatever, I mean Connor did make a promise.
So, the latest update... its just pretty fast and dirty with the route options I guess and obvious pitfalls in the hospital.
The payoff in 15b is still out of order animations, but hey, dick got wet and a LI got creampied so win.
Oh wait, we don't know where any of those needles had been, clean or dirty, just gross. Connor didn't even think to wrap it up just in case, and also not overly concerned she's getting wet thinking about being kidnapped by someone she seems to have nothing but contempt for. Also, returning to the scene of the crime for the LOVE route two days later is a weird choice.
I don't know, I'm sure it could have all been done better, from the writing, the coding, animations
The blowjob animation from Joyce in front of father's photo needs polish and it can unlock before the first one from Joyce, so the dialogue here is another continuity error.
I'm primarily a Joyce/Ruby fan and Isabel's a fun excursion from my main interests, so it pains me to say I'd almost prefer the game in its entirity gets looked over and polished from start to finish in all areas prior to continuing further, just to make it all the better as a whole experience.
The NTR fans should be up in arms! Just throwing ya'll a bone, as its not my thing... (Disclaimer: I understand NTR in its various forms and the arguments that its RAPE, not disputing, not a fan but I do tolerate it from time to time if the story is actually compelling)
This boyfriend could have gotten a face much sooner and been a bigger nuisance to the entire household. For instance, showing up, strung out, high as a kite, not a nuisance in a sexual sense but random appearances that whomever is home has to deal with on the spot. Increasingly desperate for drugs, or Isa, but mainly drugs. Then this could setup a scene where the ex is literally kidnapping and trading Isa's body to the dealer for drugs for MF, MFM, or MF+sloppy seconds. So, if this hospital scene does go all wrong as it is, still a pretty poor attempt at NTR.
Sorry for structure, I typed shit, then I added more and might ramble here or there but I'm tired now. Cheers. Looking forward to the next update to see where things go.
