Sounds good! Lmk if you get stuck on scripts. I had a pretty nasty encounter with them simply not working the way I wanted and so I got pretty familiar with working around whatever the issue is. I'm sure if you do a little research on airlocks/space stations, you'll find a color theme you really want to use and maybe narrow down the scripting to the exact specifications to make it as realistic and playable as possible.
Looks awesome! And that airlock is an awesome feature! Summoning @Egggnog . He's quite good with scripting as well. If you need an idea to fix button spamming, he figured out a good way to prevent that. I put together a tutorial on YouTube of an elevator he created where that was a thing he implemented. It might help you to check it out, since I don't know when he'll see this. Link to it can be found in my sig.
