Classic concept with classic graphics, mini games, flixel, and everything else it could ever need to succeed. However, in the process, you got some stuff wrong. Nothing that can't be fixed tho : ) (hopefully you will! I think it's worth it)
On the recipe page, you tell us 5 cups of lemonade are made out of 3 ingredients, water being free. Thing is, it doesn't make 5 cups, it makes only 1 cup! with 10 sugar cups and 10 lemon cups, with a 3:1:1 receipe, I should be able to make 50 cups, but I can only make 10. Please change the recipe text, at least.
I'm guessing you are using Number variables in AS3? If so, you could try the toFixed() function on your number variables to display a fixed amount of decimal place after the point. Like this for example, x being a number: trace(x.toFixed(2));
Why tell the player the weather AFTER the recipe choice? I think it would help the player make a strategy by knowing before. The only choice we can make with weather is price and number of cups.
Also, make the controls consistents. Just X and up,down,left,right should be enough for everything in this game (like dropping sugar should be "down", or even "X", not "C"). No need for a,s,d,c, whatever. Then implement a control scheme that could be adjusted by the player if you find people needing more options.
The laundry thing, I got confused because nothing worked when I was there in the tutorial, only to find the minimum price was 10$ afterward. At least say something to the player, I dunno, a price list maybe, on the wall?
cheers!
