Chain Cascade Part 1

Add this game-feel effect to my 2D game: Chain Cascade — Chain Counter Pop.

Reference scene (context only — map it onto my own characters and sizes):
A match-3 puzzle board, seen from the front, during a chain reaction. Art is pixel art: each piece is about 10×10 art pixels drawn at 4px (about 40px on screen) on a 44px tile grid; the board is 7 columns × 4 rows with a dark checkered background (#1d1410 / #261a14) and a 6px brown #5a3a2a frame. All sizes below are screen pixels at that scale — scale them to your own tile size. Times are seconds, t = 0 is the moment a match clears. Five piece types: mint gem #5BE3B0, gold coin #FFC24B, pink heart #ff5a7a, orange flame #FF7A3D and silver star #d8e2ea, all with a dark #1a1014 outline. Once per second a line of 3 (horizontal or vertical) clears in 0.16s (white flash, quick shrink). From t = 0.22 the pieces above fall into the gap (easeInCubic; 1 tile by 0.36s, or 3 tiles by 0.46s for a vertical match) and new pieces drop in from above. The landing makes the next line of 3, which glows faintly before it clears one second later — so each clear is the next step of the chain. A counter beside the board reads 'CHAIN x2', 'x3' … 'x13' and steps up on each clear. Sounds: a rising chime on each clear that goes up one semitone per chain step, and a soft clack when the pieces land.

The effect:
On each chain step (t = 0 is the clear), draw the chain count as pixel text 'x' + n (n goes 2, 3, 4 …) centered just above the cleared group (keep it inside the play area). …

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