Tainted Elysium was definitely one-of-a-kind! I hope someone will find inspiration from its systems and interface, because they really were innovative~
You’re right about fenoxo’s games. There are a few amazing scenes here and there, especially if you like stuffing from breastfeeding, but weight gain doesn’t feature in many scenes. That isn’t to say there are no scenes at all! There’s a pair of scenes in Corruption of Champion’s bakery that are among the best I’ve ever read for weight gain and stuffing. You owe it to yourself to at least make it to those scenes!
