This game hits my fetish buttons. Lots and lots of impregnation (both consensually and sneakily), harem aspects, a branching story where many choices at least somewhat matter, and so far no incest (which is a huge turn-off for me and a black mark on a lot of games I would otherwise like).
The English grammar could could be better, although the 'engrish' feels like it fits with some characters (such as Anna, who, in my imagination, is FOB).
There are a lot of renders in this game for such a small file size, but they are in low resolution and many/most of them look like they should have been left to run at least 2/4x longer. Not a deal breaker for me, but they do look grainy.
I'm very worried that this game might never get finished, though, because by the end of content (as of this writing) there are at least 4 characters that may or may not be pregnant and may or may not have certain kinds of relationships with the MC based on choices that were made. That is a huge number of branches and TONS of work for the dev.
Overall, though, I think it is great and I'm giving it 5 stars because I really want to see more of it.
