Kill Luigi

You control Mario, and your only goal is to catch Luigi. You run automatically, so the gameplay is about timing your jumps with the spacebar. You leap over rolling turtle shells and gaps in the path. Grabbing mushrooms gives you a burst of speed, letting you close the distance. The challenge comes from the increasing pace; the obstacles come faster, and a single mistake sends you back to the start of the level. It feels like a relentless, focused sprint where every input matters.
