As long as you're not asking every day, you're not an asshole for asking for an update.
But nope, there's no hard ETAs due to the fact there will be a UI overhaul/Gallery/Animations/Music being added in the next version. Though free readers like on Itch and such will be stuck on v0.6 until v0.8 comes out as I shift from releasing it in two weeks after paid to see if it gets me more patrons. (Due to the fact my Patreon/SS is stagnating and also very low CTR to my Patreon/SS, I get like 1k something views a month on Patreon which is nothing.) That being said, I'm still not done writing v0.7 yet either (getting close), though it will be like Chapter 5 where you have a lot of things happen before any choices.
You flatter me, I just do my best to write a silly story in the way that I want and it makes me very happy that a lot of readers enjoy it. (Especially with comments or the end survey, it helps me keep going.) Humor has been the most challenging part to write for me as I don't try and force jokes, plus it has to make sense too. I do enjoy it being canon that I self insert myself anytime I want :P
Thank you so much for reading my silly AVN!
