Need clarity on platforms

[Neurotic]

I haven't really found a definitive answer on this after searching and could use some clarity.

The versions of the game are on Steam, mobile, and Nintendo Switch. I know from reading the pinned post here that mobile development is handled by a third party, and it also looks like the Switch version is being handled by a different third party. My questions are:

Do these three different versions have feature parity? If not is that the eventual plan?

Is there cross-save between platforms or is it in the roadmap?

Seems like it would be difficult coordinating between three different developers when pushing out any updates. I have the game on Steam and I really enjoy it so far. The idea of taking it with me on my Switch or my phone is appealing but I cannot for the life of me discern if they are the same or if that is the goal.

I got it on Steam and Switch and they seem identical. No idea about mobile though.
