2D Flame & Smoke practice

[翻译] : 大家好！很长时间没有更新了，但我学到了新的火焰烟雾行为知识。我想在那之后我应该做一些水练习动画，然后再做一些全屏宽的动画。

Hello everyone! Pretty long time without updates, but Ive came with new knowledge about flame  smoke behaviour. I think I gotta do some water practice animations after this, and some full-screen wide animations later.
