TNT Survival is a more of a survival+ minigame, its meant as a fun intense challenge.
The amount of time can be adjusted in the beginning of the game using the menu:



Timer can be changed to 0:10, 0:30, 1:00, 2:00, 5:00, 10:00, or 30:00 mins, after the timer hits 0, BOOM! a TNT will go off on your location automatically.

Help
If you encounter a problem or issue with the datapack, and if it hasn't been covered here, please let me know down in the comments
(Any useful helpful information will go right here if needed)

--Game Bugged Out?--
you might need to restart the datapack, simply type:
/function tnt_survival:fix

--Can't get the datapack to work?--
try using the command: /datapack <list, enable, disable> and see if "file/TNT_Survival" is there
if it is then you might need to enable it.
(note. the datapack isn't installed if it doesn't show up on list, disable or enable)
(note2. if the datapack still does not show up it could be a problem relating to the server's provider)
