Use the PAUSE plugin to set your entire game to pause.
Then Create a label (text) in the middle of the screen , (1. use one text and set its visibility 2.create a text)
then just use a global variable to hold the integer. then :
On start of layout -> Create Label - Set visible TRUE
Then just -> Every 1 Second -> subscract 1 from the global variable.
