It seems no time has been wasted, with the Shiver Entertainment website already receiving a few updates to its home page. Underneath the company's logo, you can now see how Shiver is a "wholly owned subsidiary of Nintendo Co., Ltd" and if you scroll to the bottom of the page, you'll see the same thing with a massive Nintendo banner on display (which you can see here at the top of this story).
In Nintendo's original announcement, it mentioned how the company's aim was to "secure high-level resources for porting and developing software titles". Shiver's focus will also "remain the same" - being to port and develop software for "multiple platforms" including the Switch.
Shiver has previously worked on porting and developing games like Mortal Kombat 1 and Hogwarts Legacy to the Switch.
