how can i purchase

You can only get it via a subscription on SubscribeStar or Fanbox (it can be one-time and includes multiple games).

ok thank you


I loved Effy's model, please put her more times as she appeared in this game

Could you share the game's music list? I'm desperate trying to find a song that is in this game and I can't find it at all, thanks and great game, keep up the great work!!

Thanks! Please check the About -> Music attribution menu in the game, it lists most songs in the game. And you can find the audio files themselves in the game -> audio folder.

I see you added this to the bundle, which is great, as I was looking at getting the bundle, despite already owning 2 of the games in there...

Which raises a question: What will happen when the next one comes out? Would I have no more chance at a discount because I already own too many of the games in the bundle that buying it again wouldn't make sense?

(I feel Itch should allow a pro-rated discount on a bundle for the games you already own... But that's a separate topic!)

Yeah, that's basically it, there's no real another way to do it on Itch.io.

You can also subscribe either on SubscribeStar or Fanbox (allows PayPal) to get access to the content. $15 subscribers get access to all the content which includes comics, shoots, videos, and games as well.

Le Bundle déjà acheté, ne permet pas d'avoir les nouveaux contenus sur Itch?

Not a new game, no.
