Retro Kirby × Super Mario Game Series Collection

A dimensional crossover ROM hack that merges Kirby's Dream Land 3 with Super Mario World, featuring an all-new '2.5D' perspective where Kirby navigates between Mario's traditional 2D planes and foreground/background layers. Kirby gains 12 Mario-themed copy abilities including Fire Flower breath and Cape float, while Mario can temporarily use Kirby's Inhale via power-up mushrooms.
