The objective of the game is to erase the amount of drawing that is mentioned by "required". The 15% is a tolerance for clearing the level. Some instructions or a tutorial level couldn't do much bad. But for the rest, I like it.
on the 'push this' level, when you have to disobey, just standing still doesn't work! I didn't push the button but I failed the level. That's not very right for me.
