Intrepid Izzy

Intrepid Izzy is a non-linear action Metroidvania by Dutch studio Senile Team (originally released on the Sega Dreamcast before coming to PC and consoles). It blends beat-'em-up combat, platforming, and light RPG elements in a bright, cartoonish world.

Its signature mechanic is a costume system: Izzy swaps between outfits — each granting different abilities — to solve puzzles, fight enemies, and reach areas that were previously out of reach.
