Hi! Thanks for feedback! Unfortunately there are bugs, but they shouldn’t be game breaking.
Spoiler
When you attach the rope to the anchor you can climb down, and the rest of the gang can climb up (from this moment on).The bug you’re experiencing is likely tied to the fact that the -sound- needs to finish playing before the scene changes.
After you get the gang on top of the ship spoiler
You have to get Ed to toss the spare battery into the open hatch
