It's so unfortunate that the DLC has one of if not the best ending to a Sonic game with a banger final boss battle but at the same time getting there is the most frustrating experience I've had with this series and it's sadly not even close (ESPECIALLY looking at you trial 5...). The new characters were fun to play but Knuckles gliding felt so janky that I just used his infinite height glitch to skip some of his platforming sections. All in all a solid but VERY frustrating DLC. (At least it's free)
