This game is a 2D pixel-art side-scrolling platformer where the player controls a ninja character and explores multiple levels filled with enemies, traps, and collectible items. The player must navigate the terrain, jump across platforms, climb ladders, avoid spikes, and defeat zombies using both melee and ranged attacks such as kunai and fireballs. Along the way, apples and crates can be collected to increase score, which can later be spent in a shop to upgrade health, mana, or restore resources. Each enemy behaves intelligently, patrolling or chasing the player when close. The game concludes with an intense boss battle that requires timing, movement, and strategy to win.
