How would i make a timer ui and teleport system like in Tower of hell?

I am not that good at scripting and such but I really needed help on this a lot.

In the future, please refer to the community guidelines before posting. Specifically, the second rule regarding questions posted.

If you're looking for a countdown script, I'd just set a numeric value that keeps going down by 1 every second in a loop.

local a = 60

while a ~= 0 do
	wait(1)
	a = a - 1
end

if a = 0 then
	[Whatever you want here]
end

In order to teleport someone, you'll just move their torso position to where you want.
