OK. Why don't you guys help me out?
Let's have a competition to select the sounds for the remaining Doors.
To qualify, you must submit an opening AND a closing sound for A Door, and both of your sounds must be accepted. The sounds must be in .mp3 or .wav or .ogg format. The sounds must be free for me to use, and by submitting them for approval you are saying that they are.
I'll give the winners a prize they'll enjoy (No, it's not a free copy of Blockland or a Steam game, etc, etc., etc.). More details on that when you win. If you win for multiple Doors, no additional prize will be given . . . other than you preventing other people from winning, lol.
Here are the Doors that still need sounds:
Cell Door: Metal jail cell type Door.
Saloon Door: Western-style wooden Door. Should have a lighter sound than a normal Wooden Door.
Security Door: Heavy metal Door.
Screen Door: Should sound like a screen door.
You can see pictures of what they look like a couple pages back, if you need a reference.
Let the games begin.

EDIT: PM me your sounds. Don't flood the topic with them please.
