Kirby's Blowout Blast
This was technically the first Kirby 3D game, and I think was essentially a sort of demo/proof of concept for Kirby and the Forgotten Land. It was a puzzle/platform hybrid. The objective was to get to the end of the stage, which was relatively easy. The tricky part was using Kirby's inhale ability to take out as many enemies as possibly in one shot, and as quickly as you could.
It was super fun, and the director of the game went on to make Forgotten Land, which is arguably the best Kirby game, so if you're a fan of that, you ought to check out Blowout Blast... Although sadly I don't think there's a way to legitimately play it since the e-shop is closed.
