It's just drawing and you can save and load! To save, first you click save, second you answer Y(Or N if you want to keep drawing, and make sure it's in caps) third you open the copy table, and then right-click on it (Use a two finger click if on a Chromebook) fourth select export. if you want to load, first you open the file, then you copy the file, finally you press the load button and insert the save(remember to remove space at the front).
Loading is very jittery, but it works.
