Kinda weird that they dropped native Linux support, given the popularity of the Steam Deck.

On the plus side, it has been ported to last gen consoles as well, so I can play it on my PS4 if all else fails.

Were those not "Kickstarter Milestone Goals"? As in, if enough people backed the fundraiser up to a certain point they're obligated to work on said milestone?

I can understand MacOS support costing a lot because Apple being the "walled garden" that it is, wants everything to be "code signed" and those certs cost money, in addition to the proper development environment also costing money. Linux on the other hand, could have easily just been volunteer work.
