The amazing part about this game is written, you don't need the sex scenes to enjoy it. Keep up the quality writing!
No really take your time to get is right, a lot pf projects start out with good-fantastic writing but its all down hill the closer to full release it gets. Take your time to write the scenes out first then do the renders after, while time may be saved doing both at the same time don't split the focus if you can. As the addage goes, good characters can carry a shitty story but shit characters can't carry a good story. (although h-scenes are thrown into the mix they don't feel out of place to the story).
