I'm pretty sure all of you haven't heard from me.
I don't submit creations much and this my first post.
I have a suggestion.
Fire shouldn't create smoke afterwards!
Why? Here's Why!
*Commercial Music Playing in the Backround*
Think of it as this: lighters do not create smoke but still have a flame.
I think smoke should be created only when something as: wood,oil,etc.
As mentioned before smoke smothers a consealed flame.
Or like heat simulation mode; have a button that turns off fire created smoke.
Please and thank you in advance.
(Sorry, for any spelling/grammar errors. )

But Powder toy creates visible smoke!
In real life you don't see visible smoke.
