I've been curious about the work of this developer for some time, but was never able to make any of his previous titles work as a mac user. So I can be considered a new consumer of content from someone who seems popular.
I don't play many Unity games, since rollback is so important nowadays. A single errant click and you can miss great art or part of an important scene. You really need to play this more like a mainstream game, and remember to save frequently. That's not a bad thing, just an observation and comparison to the more common renpy games I play.
This definitely looks like it's going to be a grind. How much of a grind remains to be seen, as things haven't really progressed beyond five or six game days. I have a suspicion that you may have to do things just right to get a harem ending here. So, the question is: is the juice worth the squeeze? Should I be eager to grind for the potential payoff? That partly depends on what you think of the artwork. I find the three ladies plenty attractive, so that's one hurdle passed.
OTOH, I'm not seeing any animation. A few years back, that was pretty normal. In fact, a lot of the animation back then was so slow and janky that non-animated games were preferred by lots of fans. But things have progressed by leaps and bounds, as the tech became easier to use and indie devs gained greater skill. Nowadays, I don't spend a lot of time on games with still images. Playboy is over. Activity is the future.
Obviously, shortcomings can be overcome by either unique gameplay or a good story. The story here is decent, but it isn't going to compete with PGTE (for example). The basic premise is pretty standard (amnesia) with some supernatural mystery thrown in.
Over all, it's an OK experience that seems just a little behind the times. That's gonna be three stars from me, dawg.
