Free Pixel Loops is 20 looping pixel art effects for 2D games: 7 fires (fire at 32, 48 and 64 px, plus blue, green, violet and gold flames), 6 smoke columns (gray at 32, 48 and 64 px, plus dust, green and steam) and 7 auras, a glowing ring on the ground with motes rising (arcane at 32, 48 and 64 px, plus gold, green, frost and fire).

They loop with no jump. The 32 px loops have 12 frames; 48 and 64 px have 16, at 12 fps.

Each effect is a PNG sprite sheet with a JSON frame map and a Godot SpriteFrames file that already loops. Drag the .tres onto an AnimatedSprite2D and turn on Autoplay. Set Texture Filter to Nearest so the pixels stay sharp.

The pack is CC0, so you can use it in anything, commercial included, with no credit needed.

The effects are drawn by code with Puff, a pixel effect generator (https://cs5475.itch.io/puff).

Want one-shot battle effects too? Spells, heals, portals, slashes, projectiles, buffs and explosions, made the same way and with the same Godot SpriteFrames files, are $9.99 for all seven packs, and 20% off until Nov 17 (https://cs5475.itch.io/pixel-battle-effects-complete). Those aren't CC0: use them in any game, commercial included, but don't resell or share the files.
