renders are decent I guess
The dev chose to make this project a sandbox that plays like a VN because they don't know what a sandbox is, or what makes them fun. So, the only things that you can do are: Go to each room, talk to people that cycle through new lines of dialogue so that you can tell that new things are being added, go to sleep. Repeat about 5 times until you are brought to the main menu against your will because you've reached the end of the update, which is a direct contradiction to the "sandbox" tag.
The "updates" also leave a lot to be desired, and when I say a lot, I mean you would be forgiven for thinking that there wasn't an update and that you had just stopped halfway through the previous update and forgot to continue. Each update is almost indistinguishable from the last, in both renders and lines of dialogue. I typically enjoy the slow-burn stories that build up characters and make you care about them, but this... at this rate you will either wait years for more mediocre VN gameplay disguised as a sandbox, or the dev will just say "fuck it" and start spoon feeding nudes to people in the hopes that they will stay subbed. Either way, you probably won't get what you are looking for in this game.
