Sure, happy to chat.
Just to set expectations, I haven't worked directly with a traditional publisher as a solo indie developer, so I don't want to overstate my experience in that area. That said, I have worked on projects that received platform funding from Oculus (Meta) and Magic Leap. Those relationships involved funding agreements, dedicated contacts on their side, milestone and release deadlines, and platform-specific requirements, so I have some experience with that side of commercial partnerships.
On the indie side, a few years back I also licensed my own VR games to VR arcades and negotiated licensing agreements, and in some cases, exclusive rights. so I've had some experience negotiating commercial rights and exclusivity agreements.
None of hte above is the same as signing with a traditional games publisher, but if that's still useful, I'm more than happy to have a chat and share anything that might help. You can reach out to me on Discord (username nostalgicbear) or I sent you an email a few days ago regarding an out of memory error, so you'll have my email (which should be recognizable based on this username)
