I love this game, but its best thing is also its worst: it's fun.
It sounds strange to say this, but since it's both erotic and fun, it turns out to be extremely addictive.
Now seriously.
One downside is that the main story doesn't move forward, at least in my opinion.
The last time I played was last year and nothing of the main story has changed, just things like the events with clients and the backrooms and others extra stuff. Don't get me wrong, they're extremely good, but I'd like to see the main story go forward (things like the mc's sister for example).
