NO!
I'm talking about a door opening when you press a switch. I'm not talking about slime being emptied from a sector. Actually in THZ2, the door doesn't open. The door is already opened. The switch activates the slime to lower to the bottom. Get a liquid shield and get to the finish. You'll see that the door is already opened. If you have a liquid shield, you don't have to press the switch. Just get to the finish! Anyways, the first zone: The Gate has nothing to do with slime. It only has to deal with pressing switches that open doors.
