I think part of what makes Wario Land 3 confusing is how massive of a game it is. Unlike 4, which a kid could beat in a single weekend.
But yeah, after you beat Rudy, the game can get pretty confusing. Especially if you take a long break in between. I remember doing the same thing when playing...
If it could be any of them, would love to see a remaster of Wario Land 3 and maybe Grezzo the team behind the Link’s Awakening remake take a crack at it. MercurySteam the team behind Metroid Dread would be a great choice too.
I can see another Canadian kid asking his Mom for a Switch 2 and she's just like "sure, son." And then takes his switch and draws a 2 on the back of it and says "have fun!"
