How to Play

Getting started with NSMB: Battle R is a quick and exciting process! Launch the game in your browser via itch.io and prepare to join a lobby of adrenaline-fueled competitors. Once the race starts, your goal is simple: outpace everyone else to the finish line.

Use your keyboard arrows for basic movement—left/right to steer, up to accelerate, and down for quick stops or defensive maneuvers. Jump using the Spacebar and interact with the environment to dodge hazards or find sneaky shortcuts that give you an edge. Keep an eye on item boxes: snatch up nerfed powerups to gain temporary abilities like speed boosts, shields, or tactical traps, but remember every item has been finely balanced for fair play.

NSMB: Battle R offers settings to toggle player collisions—experiment to see what style suits you best. Full collision mode amps up the chaos, while no-collision puts pure speed and skill in the spotlight. Use the in-game minimap to track opponents, anticipate turns, and plan your overtakes—even a single misstep could cost you the lead!

Beginners should focus on learning track layouts and mastering timing for jumps and item usage. Veteran racers can capitalize on advanced movement patterns and exploit custom map quirks for hidden advantages. No matter your skill, keep practicing, study your rivals, and always be ready for last-minute surprises. The finish line is just the beginning!
