That said, I always saw the "core fantasy" of the experience as developing a relationship with your pet(s). I liked having to feed my pet, and read books to it, and then it would talk to me back. Playing games and going on adventures were framed as being done "with" your pet. The pets were well-drawn and cute, and the higher-level cosmetic items were expensive but very desirable.
From your page, I wasn't sold on that fantasy, or any fantasy in particular. If you look at the popular pet-care games nowadays, they have a fraction of the features you do while still (clearly) striking a chord with a huge number of people. Maybe part of it is because they focus on that relationship more? Especially in today's world -- but even back in 2000 -- I think features like games, items, stats, etc. need to tie in to some sort of greater fantasy in order to catch interest.
You don't have to care about any of this though, especially since you're making it for yourself. It looks fun and the tech stack seems awesome.
Is it actually possible to play minigames without creating an account? I couldn't figure out how.

Yeah, I definitely hear you with regard to the "greater fantasy" aspect. Some other players have also recently mentioned their desire for more fleshed out lore. It's something I personally struggle with but I should definitely do better in this regard, as I do want mochia to be enjoyed by more people.
You currently can feed your pets, give them toys, and read books to them (each book also has unique text that you can read inside, often with secrets about the world), and your pets should reply with their reaction (as different pet species like different things), but I agree with you that a lot of these interactions don't really "sell" themselves, and they certainly deserve more polish.
And yes, the minigames don't require an account. My apologies, I should have been more clear in the original post on exactly what a minigame is in this context. These are the locations that start off with a black tutorial screen, and then generally involve a game loop. Most other locations require an account because they require making a request to the server, but minigames can just be played entirely client-side just for fun. Here's some of my favorite ones that don't require a login:
