Writing is completed and will be fully in with the next update. I am only doing some minor SFW art here and there to enhance the experience with it. Art itself will take a bit though as there is much to be illustrated. ^^ I wanted to have an update out last month, but looks like it might be the start of August until it is ready or later as I am waiting for some NSFW art as well.
In any case I am glad you enjoy it. The Arousal scene is a nice touch, albeit may it be one that is a pretty lonely scene as the Arousal stat isn't used for anything else. Something I probably should I have planned better in hindsight. Though the real heart piece of the game could be said to be the Hidden Scenes for the Lover Slut Route. Three in total and one before each Firewall. First one activated by not cumming inside Gomamon repeatedly and being a tad selfish. I tried to drop hints in Idle Chit Chat for those, but even those hints might be easily overlooked. I do hope you will have a lot of fun in the future with this game as well! =3
