The Oxygen Update

Yay, added oxygen amount control and make more realistic (and also more abstract coz the planks have no texture :))

You can now control oxygen supply by swipping left and right (almost like using the Bunsen burner lolz)

The wood pile will have more venting space or less depending on the "openness" of the pile, as you have selected.

The openness will only update when you release the click!

Enjoy, and please give comments if you want to see this game grows!
