The gameplay involves solving a multi-step puzzle in a cartoon submarine-themed room. The first clue is found by looking through a periscope, which shows a sequence of scenes with a specific number of clouds: first 3 clouds, then 4 clouds, and finally 2 clouds. This sequence provides the password "342". The player then uses this password to unlock a safe, which contains a sliding tile maze puzzle. The remainder of the video shows the player successfully solving this maze puzzle against a timer.
The in-game language is identified as Serbian/Croatian/Bosnian.
