That'd be great. I mean, I can only speak for myself, but while I don't particularly like to make monthly payments, I'm completely fine making one time purchases if it's a game I quite enjoy, like this one.
Still, I realise that it's not your post or anything so you can't edit the link to Steam inside it, but maybe a mod can (?). While adding the link to your profile (or your signature for that matter) may help some, I believe the link on that particular post would (hopefuly) help boost your sales more. People are lazy (myself included), so they'll probably not check your profile directly when they land on

But if they see the link to Steam/GOG/any other store at the start of that post, and they liked your game, some will at least check to see how much it is. Kinda the same thinking why you have those candies near the register at stores; it's an impulse purchase because you have it there, visible. And at least it works on me, with some games that I've really liked. I looked up the game here, tried them, and if I really liked them and saw that they had it available at Steam/Itch.io or something like that, I'd buy them directly. If not, well, sorry to say, but at least I don't bother to look for the develpver otherwise. Maybe that's just me though.
Welp, that's my two cents at least, as someone who studied a bit of management for a time lol. And it's just my idea, might be awfully wrong here too. But anyways, good luck and thanks for making the game!
