I love robots!
I appreciate the themes you have going in this, and I hope it becomes more heartwarming as time goes on.
The UI was pretty nice, too.
I wish things moved a little faster at the beginning. I understand what you were after with the hum-drum of work and lack of human interaction. But it was pretty boring until Ako arrived.
I enjoy that she isn't a sex robot or a companion robot, which gives the interactions a lot of room to grow over time.
The models and animations are really well done, but the sex scenes are a bit boring. Some conversation during them could give more to grab the attention.
