I'm sorry I couldn't complete 7F in time, resulting in this weird workaround. However, the integrated version will contain some extra (light) progression and post-game elements, too, so I'd encourage people who like Iris to snack on the standalone since there will be some des(s)erts later anyway. If you don't want to play it twice or want to play it on 'your' save, you'll need to wait a bit longer (few weeks) for 7F to be finished, and you can then play them in sequence. 8F is not particularly contingent on the events of 7F, so people worried about story spoilers or continuity should be fine with the standalone version.
8F will be integrated to the full Tower after 7F, which is unfortunately not done (obviously) but is getting there. Simply start a New Game and you will be right in front of the 8F entrance. Quoted from Koda 'Because it is standalone, you cannot import or export saves. Fixed rare cases of Iris skipping her hold-pose turn
Activated animations in Bath battle (Standing Battle battle has none, not a bug) Hopefully /finally/ fixed battle animations hanging/locking the game
