Well, just type in your question and then the eraser will give you a response (that is pretty accurate so far, just like an actual eraser!) I might add some animations, when I can.
Credits to my friend, @wudada, for coming over to my house once and playing "Yes/No Eraser" with me. She gave me the inspiration to make an online version, just in case you're not interested in tossing erases but still need answers desperately.
