Woah, this game definitely deserves nothing less than a 5 star. Overall it's great, fun, well written and well prepared. Even much that it saddens me seeing it actually being that underrated. At this time I'm writing this (Chapter 13) it's a hidden gem.
Unique story, unique characters and really interesting plot exploring all LIs deeply. Which is one of the most positive points I can make about this game, almost all Love Interest's own plotline created as they are the main girl in mind, you can really see the effort and thinking Dev put into the game. Keeping all of them separated but together at the same time, while giving them a distiguishable character. Really something to appreciate.
At first couple episodes things are more amateur-ish and humour is pretty dry. But as the story progress you can actually see the game progress as well, It gets better in all means, so I suggest players to not to judge quickly.
I have many more things to say but also no need for it, I feel and wish this game will be very succesful in the future.
I only have 2 little negative (imo) things I could say about it.
Honestly I would play and love this game even if it was only about Hikari, so I kinda underwhelmed by the amount of content of her, even though last chapter was entirely about her, thinking that she got into the story really late than others and even though crossing some lines several times, MC's inconsistent and unsure behavior against her is a little bit irritating, it might be Dev trying to pursue "forbidden fruit" deeper but I wouldn't call it succesfully done, It was more like trying to hurt and reject Hikari several times then get angry at both her and Sayumi over the littlest thing, compared to the other girl's arcs (especially Yukimi's) I would say Hikari deserved way better than that, but that's my opinion.
Second one is not that important, but this little breaks with enthusuastic rabbit-girl between chapters are a little confusing, I see the humouristic and cute side of it, but like what's going on, as MC we really listening someone tell a story or something?
Overall this was a really enjoyable experience so far, I hope eolo gets more support in the close future and we get to see this piece of art more.
