If I purchased the game here on itch, will I be able to download the next update here? I saw the page was taken down
As far as I understand it, as it currently stands, the game is only available on Patreon. However, from what I've heard, users should still be able to download the games they've purchased here on itch. But I'm not sure if Siren can actually push updates here anymore as long as the game is blocked.
So ... maybe? But I wouldn't bet on it.
As Siren stated in their latest v1.1.5 First Look post on Patreon, they don't know themselves if it's possible to release updates for the game here on itch at this moment.
I can't answer that, sorry.
I'd guess, wait for the 1.1.5 update, then take a look here and on Patreon if the new version should be available on itch and if it actually is. If it turns out that Siren can't update the game here on itch while it's delisted, then the only other way would be to purchase the game again on Patreon.
