This is great! I was able to get it running in Val Town: https://www.val.town/v/stevekrouse/f0_example

We built simple blob storage in Val Town, which has the added benefit of not needing an external API key if you're using it from within Val Town: https://docs.val.town/std/blob/

The API is similar: `blob.setJSON(key, value)` and `blob.getJSON`
