In Brave Warrior: 100 Floors, players control a warrior descending through levels by tapping the left or right side of the screen to move the character. The objective is to avoid obstacles, prevent touching spikes at the top, and ensure precise landings on platforms; failure to do so results in losing a life. As the player progresses deeper, the difficulty increases, demanding quicker reflexes and strategic planning to navigate traps and enemies. Each floor presents new challenges, testing the player's agility and decision-making skills.
