// This drawing tool is a simple tool which allows the users to easily create a space scenery.

// I limited the features to a mininum of options but still clearly expresses to be place outer space. 

// Also, by adding a simple drawing tool, I provided the users to have some freedom of creating some 

// content they can play within the space background.

// And by having the erase feature, the users are able to gain preciseness in their drawings. 

// The users could also save their drawings by simply pressing the 's' key.
