This game is for fun! The 'erase' button erases your pattern and gives you more options! The 'back to home page' button will bring you back to the choices so you can do more than one pattern at a time All you have to do is press a pattern! Also, with the 'draw your own' button the sliders only go to ten and then they become the ten of them (of that makes sense) if you want straight lines than just click far away from where you stopped drawing!
I will improve it and add more patterns when I have time!
