Thank You! Well, it's a short game. Thus there are also no day-night cycles. But the idea is not bad... Regarding the colour of smoke - have You ever burned plastic? And paint? Cable wiring perhaps, or old paint cans - the smoke is disgustingly black. :D
You're welcome and nope I don't like using a lighter (I'm a non-smoker & minimalist too), anyway I could imagine a car-race with tires heated in speed referring to action-movies, even scenes are rather including effects still there's maybe quite black "fog" added too, I guess.
Sure, I like just the fact of adding parts that sound cool in aesthetic, so users could enjoy even adorable or realistic graphics there. Anyway coding and perfection sounds cool but maybe takes time for creating without any bugs ...also why I prefer to stick to non-animated stuff.
