Fun gameplay weighed down by awful micro-transaction bait. The game wants you to buy gem apples, and it tries to do so by locking everything behind them. Unlocking bosses, weapon/armor upgrades, and resetting your stamina all cost gem apples. Sure, you can earn them (very slowly) through missions and logging in, but it is such a time investment that you might as well spend money. (Please don't.)

This all applies to the Switch port as well. Both are not worth your time, just play the mainline Kirby games instead.

(Also I love how the game description markets itself as "free-to-start" instead of "free-to-play", as if it's assuming you will eventually give in and pay...)
