the cursive plaintext snake writer
* new so it still works pretty bad
* you need your terminal to 80 characters wide and 30 characters high.
* now support for any size of terminal
* use w,s,a,d to move the snake use q to exit and save the snake
toekomstmuziek:
* build a more TUI like interface where we don't clear the screen
* removing the flasing effect while drawing.
* put a blinking cursor where the snake currently is
* implement pen-up and pen-down
