Guacamelee! Super Turbo Championship Edition is coming to Switch today. Drinkbox Studios announced the stealth release in a press release, adding that Guacamelee! 2 will arrive on the Nintendo console sometime in December. It won’t have any additional content, but will support up to four players with the Joy-Con.
This is Mark of the Old Ones, a physics adventure-platformer with a Lovecraftian twist in which you're some sort of a tentacled abomination. Watching the trailer I'm reminded more of Gish than anything. A really pretty, horror-themed Gish. It has an ongoing Kickstarter campaign, if you're interested.
