On the Subject of Mystery Widget
Not a boss, D@M.
This module will hide one of the widgets on the edge of the bomb until it is solved.
To solve this module, solve the module on its display. The display may then change.
When the display starts flashing, hold the button across exactly three ticks of the bomb's timer. The module will then solve, and the widget will be revealed.
Note: If the display is impossible to solve, you may activate the failswitch. To do this, hold the button across one tick of the timer. This will remove a fifth of the time from the bomb's timer, then the display will change.
