The game is not completed, it's more like a demo. However, rather than a "cliffhanger", I'd say it ends on a softer note than that, as you're not left in a big suspense of what's going to happen. They hint at what might come afterwards, but you never get to see it. Except for, perhaps, Bengan's route, as there is something really, REALLY interesting going on with him but unfortunately it seems we'll never get to see it. I felt like this wasn't enough and I wanted to see more of characters and find more about them, but as for the story, it doesn't leave you with too many questions to be answered.

For example - with the options I chose to romance the characters - it felt like the characters warm up to MC pretty fast and are returning the interest/affection I chose to show. So, I never got to see it, but I was left with impression that, after the working hours, they are very likely to try to get to know MC more (in romantic sense) and perhaps make a move on them. But yeah, it's such a pity that we actually never get to see it.

I hope I managed to explain it well without spoiling too much!
