Minor update, R-15 version was updated for probably the last time. The update notes only indicate a buff to the purification stick...I thought more improvements from R-18 would be implemented, but it could be incomplete. DLsite's updated, Steam's still pending it looks like. Unless the description on the page just wasn't updated.
R-18 version's being submitted to Steam now, Nana's working on getting a bundle for R-15 and R-18. See how that goes. One somewhat minor bug left to fix and touching up on a couple animations and that should be it for the game. Discussed Steam sales a bit with Nana, at this point in time the R-15 version has sold over 400 copies. Given that the first month was about 70-90 copies, I'm surprised it ended up being so much, though Nana was like "the sales aren't that much, it's a big market but the competition on Steam is fierce". Between JP DLsite (1,000), EN DLsite (240), and Steam, Steam accounts for about 25% of the game's sales. Of course, Nana's concerned that Steam won't accept the game due to the loli H content, there's still that possibility that it won't be accepted. Gonna have to wait and see. I'm helping with the submission process as Steam doesn't offer a Japanese translation of the site, I'll update again when there's more info on that.
