As the creator says, this VN starts out okay but gets better in the later parts. Haven't finished but so far I'm entertained. Looking forward to the revised opening.
I will say this: the story and characterization make WAAAAAY more sense with the incest patch installed. Even if that's not your cup of tea (I don't particularly mind it myself, YMMV), it still serves the story far better. Alex and Iris's relationship dynamic fits better, and a major plot hole is explained away perfectly.
Biggest flaw: this needs more BGM. A single track on a 20 second loop becomes infuriating after awhile. I ended up muting the sound because it was driving me crazy.
