(only seeing this game now because this is the update making it playable on web)
Seems like a pretty good start, the graphics for the girl and the scenery are good (though the cock graphic is a bit weirdly shaped), the customizability is a big selling point. However, I feel like it is missing some rather obvious additions.
Recommendations for things to add:
Presets for the girls
Ability to cum inside, and do it without clicking the button on the lower right
More color customization (or, a clearer interface for it, since it is possible that I am just not understanding how to do it right)
Also, upon right clicking to change the angle, is it supposed to... suddenly snap the angle to the side like that? Seems like a bug.
