I have some Catching up to do...

So this is my level layout in UNITY.

 Here is the first room you exit from, it has 8 Pods and an open pod!

Here it is with the fire effects. There is light flicker effects also and different sounds.

 Door with animation, will show in my video!

 OPEN!

 Clearer view

 Open Pod.

The code at the end jumps to my terrain level!
