Yes!
So as of…about five minutes ago, Spelunky 2was only slated for PC and PS4.
But now, as part of today’s Indie World Showcase, developer Derek Yu has revealed that both the original and the sequel will be available on the Switch together. Yu confirms that it’s arriving in 2021, with both local and online multiplayer.
Later on in the broadcast, Nintendo confirms a “summer 2021” window for both titles.
