Don't get me wrong, your drawing is fascinating. But as a h-game (which I saw it on a h-games forum) I expect some good stuff (fap material to be honest) which I couldn't find except a man throbbing his D. He wants bj but nothing shown when you comply. (Maybe it's because it was just a demo?) So my opinion is it'd be better if we are to observe it by first person or third person.
The story progress well and I can feel the grim atmosphere. The faces are creepy and fits perfect. But as a h-game it offers almost no content. So on the h-side it felt dull and empty. Sorry for my harsh comment with no context earlier.
This game reminds me of "LonaRPG" by drawing and atmosphere. Both games are great to make you feel the grim and desperation of the world. But for me, Love lock lacked the h-content that Lona gave.
I wish you good luck with your game and I await future updates.
