It's short.. But it's still technically "v0.0.2", so it makes sense that there's not much content..
The english can be pretty bad though, but I'm kinda used to that.
And when a game is still in its early stages, chances are, it's still only being worked on by one person, without any proofreaders or story script editors. So the grammar gets a pass for now..
The major flaws, in my opinion, is that there's no dialogue or text during the sex scenes.
Adding text or dialogue, can not only make the game last that much longer, but provide context, and help with transitions from one sex position to the next.
Without it, the sex scenes just "feels" boring. I mean, yes, it's animated and it looks good, but I can get the same feeling from just looking at a GIF gallery.
