Move and Save is an arcade game, in which you should avoid hitting your fingers with saws, to achieve the best result. If you hit with one of the saws, the game would stop and you would see your score at the screen. Also if you move away your finger from a screen, you would be given a warning.
There are three modes : easy, medium, hard. To choose the mode, tap a button in the main menu.
Good luck and have a nice game.
