To be honest I am much more frustrated it seems than this guy here...
I bet it could be a good game but there's so much lack of everything that would make it interesting for me sorry to say.
The story is really boring because everyday seems like the others. I do like the main characters besides the Q&A guys ( they're just weird except the actor ;/ ). They have different hobbys and personalities. The artwork is pretty good from what I can tell. The backgrounds aren't blurry, that's really nice, but it isn't a thing that makes the Tennis Ace VN worse than others at all (another gay visual novel).
I dunno if you have ever played another gay VN but you propably should do it. There are some really good onse here on itch.io (most of them fantasy themed though) with an interesting story line, great artwork and interesting characters.
(I could suggest some if you want, even though I don't think it's necessary)
So, I hope you are able to afford more one day, if it is what keeps this novel behind.
Since I assume that others are into especially this VN I won't judge you. These are just some thoughts of mine. 4 out of 5 stars from me because it's good developed :)
I hope this helped a little... I felt bad so don't you worry I supported you anyways ;)
