Re: フォクシーブレイド
As far as I can make out from their blog,
the update is mostly bugfixes, as well as an "easy mode" switch in the basement that gives you double HP.
They're also talking about a sequel, where they will expand on arousal and state change mechanics, and maybe focus more on the boss fights.
Also a separate "fan disk" update that'll add some sort of pleasure meter to this game, will be released sometime in july, and cost 500-1000.
