We designed Fell Seal: Arbiter's Mark with consoles in mind. The game fully supports gamepads and we're in talks with Sony and Nintendo about the PS4 and the Switch specifically.
We're still expecting news from both at this point, but it's not finalized. We won't promise a PS4 or Switch version unless we are ABSOLUTELY sure we can deliver it and at this point, we very confident, but not 100% certain.
It's not a question of funding, but of approval and connections, hence why we're not making a Stretch Goal about it.
TL;DR: We think it's very likely we'll have a PS4 and Switch versions going, but it's still not guaranteed. We'll make an announcement as soon as we know more! :)
