I should also consider the possibility that "Link Exclusive" is part of a game mechanic or a special mode in the game that unlocks unique characters or stages. However, more likely, given the context of beta versions, it's about unofficial or leaked versions shared online. I need to make sure to address both possibilities but lean towards the most plausible one, which is an unofficial beta version with exclusive content.
