One of my patrons has actually been working on something for this, building on the work of an f95 member. But, the difficulty is that each scene has so many variations just based on variables/values that a traditional, main menu-launched gallery with playable scenes, is kind of difficult. So, the options at this point seem to be a gallery that launches to only one particular variation of a scene, or an option to choose, broadly, the nature of the scene, which would then still be sans certain customizations.
The other option is to have a gallery within a save file, where you can jump back to scenes you've played. But, at that point it seems like.. Why not just have save files for those scenes?
So, it remains a sticky wicket for the moment. I'd like to launch the Chapter One remake with some kind of gallery function in place. But, exactly what that might look like is still up in the air.
