That's great to hear, a Steam release could genuinely do really well for this, especially with how thoughtful and polished the experience already feels even in its early stages. The hidden object audience on Steam tends to be really loyal once they find the right game.
Since it's still in the planning stage, this is actually a great time to start thinking about visibility too, early wishlist building and page optimization make a real difference once you're ready to launch. I help indie devs with exactly that kind of thing, wishlist growth, visibility, Discord and community setup, that sort of support. I also have an Upwork account if that's ever useful for you to check my work or go through a more formal process, happy to share it whenever you'd like.
