That's a great story, Reddit kickstarting it and then the itch.io front page picking it up is the kind of momentum most solo devs never get. And the TikTok swings are normal, even strong accounts see that spread.
Since you've already proven people want the game, the next step I'd think about is Steam. A Steam page gives you something permanent: wishlists, followers, and a place where Steam itself recommends you to people who like similar games. Steam also has a festival this month, and that kind of visibility can send a lot of new eyes to a game that's already updating daily.
Setting up Steam pages is what I do. That covers the store page itself (capsule art, trailer, screenshots, description, tags) and getting everything ready for the festival. I'm also a professional video editor, so I can cut the Steam trailer from your daily clips.
I handle all of this through my Upwork account, so you get payment protection and a proper contract. You only pay for work that's delivered and approved, and there's no risk on your side. If you want, I can send you my profile link first so you can check my reviews and past work.
