Sonic Mania is pretty darn good but it can be a tad buggy at times, from minor issues to problems that have frustrated some players. It's taken a short while, but the first update to tackle fixes seems to be rolling out.
The official social channels for the mascot announced the news.
At the time of publication the update hasn't kicked in on our copy (even after manually checking for updates), though as it's rolling out it'll hopefully reach everyone soon. Rather humorously some responding to the tweet have been joking that the update is really a meme; the social media channels are reaping what they sow.
We'll keep an eye out for the update, in any case.
