Solution: SUNDAE. To select levels, there were 3 hints Easy, Medium, Hard. After opening each hints you can see checker boards where you can move a piece. First piece resolve S, medium resolve U and Hard resolve N. And after entering SUN, you open another hint saying "SWEET". If you look at the filename on each early hints, you find D, A and E as extra on filename for the images. And since SUNDAE is a sweet, it's the final answer.
