All the times I heard the file go "Oh nooo" made me feel so bad for the lil guy XD
The Nail Files has interesting but fitting music, not hard but little challenging way of moving, and many levels + even level selector. It was noted that the red parts in the level are not to harm the player, yet I felt little alarmed everytime because of the color, BUT I can see why it was used since red and blue both were the main colors used in this game. The character design of player was little creepy but I felt sympathy for the nail file, who was just trying to get back to the hand.
