We do have some plans to add some soft digestion/goo digestion stuff into the game as well as disposal scenes. We don't currently have plans to make a scene viewer since each of the scenes can already be replayed if you finish Stella's time quest.
Gotcha, on the scenes bit, wasn't sure as I noticed in the gallery that there were versions of some bits that I didn't go down the 'right path' off, so thanks for the heads up on that.
Also glad to hear you do plan for more digestion stuff and even some disposal, that's nice to hear!
