Very cool. Great work! I built a product called Asset Layer which integrates with Unity and lets you add awesome Roblox-style creator economy features to your game: things like making your assets interoperable across games/mods, making it simple to add UGC, supporting player-to-player markets & storefronts, etc. The goal is to make these features accessible to smaller indie games, not just AAA studios.

Your assets/game would be a great fit for this in my opinion. I'd love to set up a quick demo for you if you're down to learn more. Below is a quick video showing the features.
