Making Game A Little Easier

Made some small changes, as I spotted them since publishing.

1. Making the game a little easier, by giving 8 molecules before loosing (even if there's time left.

There were plans to make additional levels, with fewer molecules to drag before loosing the game. That will probably still be part of future levels, but we can keep this relatively easy until then.

ToDo:

* fix the issue with display size  Now need to adjust scale so that it can be full screen.

* fix the grey background color. It should be white. fixed
