You are Charles Goodyear, and you are in your small factory in Springfield. You only have a budget of 25 dollars at first, and chose a quality to vulcanize. Sell the rubber, and buy the sulfur. How to play: Choose a quality, (Default: Cheap) then press the Vulcanize button. Count to the number listed in seconds next to the quality selector. (E.G cheap is 10 seconds, and the accuracy range is 3-5, you will get nothing if you are 3 seconds early or less, and you will get 5 if you are perfect accuracy. if you are above 10 seconds in waiting, you will get burnt rubber, and no money). Then press the stop button once you think you have reached that amount of time listed.
Note: if you notice any bugs, report it.
