Start Battle Button - Pixelated Adventure

"Design a pixelated 'Start Battle' button that features two crossed swords at the top. The button should be rectangular with a rugged, stone-like frame made of pixelated textures, fitting the mystical island theme. In the center of the button, include bold, pixelated text that says 'Comenzar Batalla' in a bright, glowing color like gold or silver. Above the text, add two pixelated swords crossed diagonally, with sharp, silver blades and decorated hilts. The swords should have a slight shine or glint effect to make them stand out. The background of the button should have a gradient from dark blue to black, giving it a dramatic and intense atmosphere. Small pixelated particles or sparks should subtly emanate from the swords, creating a sense of anticipation for the battle. The overall look should be epic and inviting, encouraging players to press the button to begin the combat."
