Burning Part 1

Add this game-feel effect to my 2D game: Burning — Flame Burst.

Reference scene (context only — map it onto my own characters and sizes):
Side-view pixel-art scene at night. The swordsman on the left (12×13 art pixels drawn at 7px, 84×91px) faces an orange slime on the right (16×12 art pixels at 7px, 112×84px, about 200px away). Times are seconds; t = 0 is the hit. On every hit the slime squashes to 85% height for 0.12s, shakes ±3px for 0.15s and flashes white for about 0.05s, then keeps breathing (±3% height, 2 times a second). Once every 1.0s the hero casts a fireball: he leans 6px forward over 0.75–1.0s, his hand glows orange over 0.78–0.86s, and a gold #FFC24B square fireball (18px, white-yellow core, 3 fading orange #FF7A3D trail squares) flies from his hand to the slime over 0.85–1.0s (easeInCubic).

The effect:
Spawn 12 pixel flames spread evenly across the slime's width (108px), starting 14–54px above the ground, each delayed 0.02s more than the last. …

The rest of this prompt — exact sizes, easing, colors and particle counts — and full prompts 2–6 are in the pack.
