Probably trying to milk out one more supporter update before release. Well, jokes on them cause I would have died of dryness the next day with Sinisistar 2.
My guess it that when you clear the game(like finish the whole game), you will unlock some pure love CGs that you’ll probably access in the gallery, or something. I don’t know. I’m just pulling this out of my ass. We’ll have to wait next month to find out more on this. Or they will release this on the release date of the game, which I would remind again, was moved to the 8th of May.
