Golf a Compute interpreter Introduction
Compute is a esoteric joke language.
From the esolangs entry:

Compute has no required syntax and has the power to solve any and all
problems. It is smart enough to interpret any human language (English,
Spanish, Latin, etc), any programming language (C++, Java, brainfuck,
etc), or any kind of data you can think of. The only downfall is that
there is absolutely no I/O.

Some example programs
Hello World

A basic Hello World program
What is love?

Determines was love is (baby don't hurt me).
When will we ever graduate?

The Challenge
Your task is to write a full Compute interpreter. This sounds pretty hard, but keep in mind that Compute has absolutly no I/O. So your interpreter will just sleep one second for every line in the input program and output \n\nDone. after this (this is the only exception to the no I/O thing).
You can find the official interpreter at the bottom of this site.
Note that the official interpreter pauses one second for every character in the given source code. To avoid long waiting times while testing your interpreter with meaningful questions we stay with lines in this challenge.
Rules

The input might contain multiple lines seperated by a \n. There will always be at least one line.
Unlike the official implementation you don't have to take a file as input. You can take the Compute program in any form of input you want.
The only output allowed is \n\nDone.. A trailing newline is allowed.
Function or full program allowed.
Default rules for input/output.
Standard loopholes apply.
This is code-golf, so lowest byte-count wins. Tiebreaker is earlier submission.

Code:
[Ig&gt;#w’

D€µ.

Explanation:
[        # Starts an infinite loop
 I       # Input string
  g&gt;     # Length + 1
    #    # If equal to 1, break out of the loop
     w   # Wait 1 second

This part is equivalent to &quot;\n\nDone.&quot;:
      ’  # Push &quot;\n\nDone.&quot; on top of the stack

D€µ.     # The compressed string is ended implicitly
         # Implicit, print top of the stack
