Hello! Before you start telling me there is already a guide on Floor Is Lava, this is different. It’s for adding spectating as well as for easier replayability. Thank you. This will be broken up into 6 parts.
Lobby
Make a small rectangle of a block of your choice for the Lobby.

Add a button with these settings



And a lifecycle.

And wire it to the button
This will make it so that only the host can press it.
It is up to you to teleport players here.
The Base
First, make a large rectangle out of a block of your choice, like as shown.
After this, make small jumps up and down along the side of a larger rectangle encircling the first one.
Next, add a large zone covering the bottom section of the rectangle.

With these settings

After that, add a respawn device nearby.

Add a counter next to that

And a repeater next to it

With settings like this
Tech + Barriers
Wire up the zone and respawn like this
And the repeater and counter like this
Set the counter’s settings so
Next, add a barrier and size it to match the zone, like this:
Change its color and settings to these:



You should now have this:

The Top
Add a zone at the top, wherever you want the players to reach.

With these settings

Point System (Optional)
Add a counter

With these settings

And a trigger

Wire the zone to the trigger
And the trigger to the counter
Add an end-game device.

And wire it to the counter
Now, whenever a player reaches the top, they will score a point.
Spectating
Add a spawn pad, if you don’t already have one.

And a teleporter in the outside rectangle

And a repeater with these settings


As well as a lifecycle with this setting


Wire the lifecycle to the repeater
And the repeater to the teleporter
Conclusion
As you can tell, I left a lot up to you, Such as how to get the players out while waiting for the next round. I hope this works well for you.
BTW, This is my first guide!
