It seemed short so I played it.
Game design is questionable. Images are vertical. There is a weird flowchart system where you have to replay runs to get new choices to unlock more scenes. Then, at the end of the run, you can review all the scenes (so far just 2) you have seen on that run. Depending on how many scenes you unlocked, you get some small ending.
This is essentially a "completed" story, just with the entire progression missing. You get time skips of days, weeks, and even months. Presumably, the updates in the future might fill in these blanks? Interesting developmental process I guess, but it pretty much spoils the NTR progression.
The scenes themselves have a nice little animation to it, but it's super short and ends before you can really even get into it. Plus, there is some heavy Engrish throughout the whole thing.
I like the art though...
