The original artist for the game has moved on from the project, and we have talked previously about the reasons why it would be difficult to continue developing IA, or a game similar to it.
Essentially it comes down to that companies like Paypal, Visa, Mastercard, etc. don't want to see games like IA getting support or funding. A lot of people blame Patreon for purging games like IA from their platform, but in truth it was due to pressure from Paypal and payment processors.
There's also the factor that there are people out there that really don't like games like IA, and they will actively make it as difficult as possible for the game to get support by reporting it.
It's unfortunate people can't separate fantasy from reality, but that's the current climate that we're in. And it doesn't look like it will be changing anytime soon.
