Kirby games love to call back to previous entries in its series. Kirby’s Dream Land for the original Gameboy must by this point be one of the most called-back-to games ever, being referenced in clever and funny ways as early as the second “main” Kirby game, Kirby’s Adventure. (Here’s Wikirby’s page on that distinctive level.)
While a few of the references in this 1 hour, 25 minute video by torkirby may seem half-baked, they’re greatly out numbered by the ones that seem dead on. A lot of Kirby’s staff, especially in the area of music, have been with the series a long time. People try to leave Kirby’s presence, but they keep suckin’ them back in: even Masahiro Sakurai is returning to direct another Kirby game, with Kirby Air Riders slated for the Switch 2!
Speaking of which, I have a post in the works about the rising netplay esports scene around City Trial in the original Air Ride. That looks really interesting!
