s.color is not a function

[Bloemendaal]

When I use npm i scratchie to install it to my project and run the example, it gives the error Uncaught TypeError: s.color is not a function. In the file dist/scratchie.umd.js, on line 79, it says:

s.color('white', e),

If you change that to the code below, it works just fine:

s().color('white', e),

Also, there is no license reference in your JS files. Is it oke if I include the following line or do you prefer the full license?
