there is some in the public , but the proper full gallery is for patreon supporters of the game development.
this is confusing, a few comments earlier it sounded as if we simply don't get a gallery mode, now it sounds like we get the worse version if we play free and barely any scenes.
If this is about paying I am one of those prefering to pay here instead of patreon and maybe it can be combined with a steam key. In a few hours I will take a closer look at the game.
