Short brass pipes protrude from the corners of the bulkhead. If a pipe bursts, a jet of water gushes out. Press a finger against the nozzle, and the water stops immediately; release, and the water level in the bilge rises. A maximum of five leaks can be plugged simultaneously with five fingers. Each watch lasts only a few seconds: the large numbers on the left indicate a leak in the bilge, and the golden countdown on the right shows how much longer you have to hold out.

Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be.

The accent colour we picked up, #3C5C6C, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
