I updated the challenge so one can choose from those levels. I thought that you might be interested where the user could specify the size, but I do not really feel like it would be great. I mean it would need validations, also if there would be a very big maze like 250 x 250, 3 coins would be too few I think... :)
I didn't think about number of coins vs size. You're right
