Press any button to stop the alarm when it's done. Press the tiny sprite in the top right corner to start a timer. The program will tell you the rest. DO NOT PUT IN A VERY LARGE NUMBER, A NEGATIVE NUMBER, OR A NUMBER THAT'S NOT A WHOLE NUMBER!
I was just bored and made a timer. Official Release (V 1.0): Released Timer. Anti-Confusion Update (V 1.1): Took Away Confusion.
