I feel like that would be more based on the AP protocol raw, so it would be closer to another fedi frontend like lemmy or masto, that can be interacted with from either
it would be kind of neat, have it display like an updating stickied status post or just on another site entirely, then have posts where pixels are submitted as comments.
I still think the platform itself has a lot of development work ahead of it before at least the main developers could even think about games/social experiments like that.
