Hello. Can i first say from what i saw this is a nicely put together idea, however there where a few things i noticed. After you descend into the part bellow the ship to pull the lever i found myself unable to climb back up without moving the ladder down a bit, is this intentional? The lever for the storage room door is frustrating to get to, the idea is really good but maybe a few more hand holds would make it more fun and less irritating. When i pulled the lever, creepers spawned and destroyed the floor and the red stone wiring bellow was destroyed shutting the door permanently, maybe zombies would be a better idea at that point. I found the "key" But after that i could not find any way to progress, is this the end of the adventure map so far. All in all i enjoyed my time, and i would like to help any way i can.
