706C: Render balloon
Renders a balloon enemy sprite at the specified X position. Balloons are 2-tile wide animated objects that float above the river. Unlike other enemies, balloons disable collision detection during rendering.
  • Disables collision mode via state_collision_mode (allows plane to pass through during render)
  • Animated sprite with $20 byte frames at sprite_balloon
  • Dimensions: 2 tiles wide (16px) × 16 pixels tall
  • Attributes: $0E (PAPER RIVER, INK BALLOON)
