Ok not saying the game is bad, but I have to say I don't find it particularly interesting.
The girls are kind of plain, none of them seems to have defining traits or truly unique personalities, the ony thing that differentiates them is their backstory and the fact that their features all look similar too does not help at all.
None of them has any particular flaws or strong points. I feel like they all fit into the same box, they tend to react to their issues in the same way no matter how different their past or heavy their load is.
They all feel like the same girl and they act the same towards the MC; they all obviously like him right away, want to be with him, immediately try to get close and appreciate the help and support he gives them, responding positively to the same kind of attention.
The game is not terrible, as I said, it's just that I personally find it kind of boring. Could have been much better with a bit more thought put into the creation of the characters; maybe make less of them relevant but develope the important ones better next time. Probably overambitious in regards to number of choices given. Cheers.
