I am eternally surprised whenever devs dont implement a good Gallery / replayer. All that energy on scenes, only to have them be one-off.
If the dev ever looks at this:
Step 0.5 (because this should already exist): Have the start-moment of scene be callable in code from more than one location. IE dont make the code so messy you can't enter the scene from anything else than one specific method.
step 1: Set flag at beginning of scene. Flag is a boolean indicating whether player arrived there from gallery or not.
Step 2: In gallery, when pressing the scene, take player to the exact scene, not the still-images. At the end of scene, check flag set in step 1. If it is true, return player to gallery view.
One can dream. Such a great game, just wish i could replay the scenes.
