I can only speak for myself, but my game was making me about $1,000 a month and I've sold $60 this past month. So, I think everybody is really scared right now especially because they're saying that PayPal is banning people's accounts for purchasing NSFW games here. Which is just a whole another level of crazy dystopian. So yeah my itch, is essentially, dead.
I check the main blog every single day in the hopes that itch is going to announce that all of our games have been re-listed and that there's a new payment processor or something. But no luck yet, it's abysmal. I don't want to discourage you from uploading your game obviously, but you may not really sell very much right now until people can dispel whether or not PayPal is actually deleting entire accounts.
