Hi, I'm learning the game starting today and I was wondering if there was any sort of tutorial for the game.

https://kb.speeddemosarchive.com/Kirby's_Return_to_Dream_Land

That's a really comprehensive resource on the routes, game mechanics and boss strategies. Might be slightly outdated but still really well done.

That and watch the vods for some of the fastest times, maybe some of the ones lower on the line for more beginner friendly routes?

Good luck!

Thanks!
