Mario against Kegare. Honestly, this is the 2nd best 3D Mario after Odyssey. If Nintendo makes this bigger, a la Sonic Frontiers but with actually good to great level design, it could become the best 3D Mario ever.
Originally played this on the PS2 collection. It is a cool, beautiful, and challenging platformer. It should have become a franchise, like a certain blue hedgehog
