I intend to have a Steam page up for 'Miniature Multiverse' fairly soon.

Until then, please just focus on the Itch.IO page for that project. 

If I can get that game to succeed on Itch and Steam, this year... well, it's entirely possible that some of my other indie game projects will go onto Steam too in the future.

But it costs, what, $100 per game listed on Steam? So little minigames aren't likely ever going to make it there. (Sorry, Spiral Skies!)

All the more reason to look at Itch.IO for now:

The banner links at the bottom of each page include links to my own webpages, links to my storefronts/shops online, and occasional links to other [third-party] verifiably legitimate stores and services I've hand-picked, vetted, and used myself. 
That said, I'll openly disclose that when you buy something from another vendor using these links, for example, a link to Amazon.com, I will get a small fraction of the sale amount and will use that as a means of supporting and expanding the projects I'm working on here. These ads for other vendors, as well as - especially! - links to my own shops, are helping me keep these sites online and growing with new content on a more frequent basis.
