Wavetailer: steal gold back

Play Wavetailer as a pirate who spent many years on a ship, looking for a mythical island with ancient treasures. In the end, the goal to win is found - but not everything is that simple. While you were getting there at Wavetailer, the cunning octopuses wanted to win too and already managed to steal all the gold and hid it on their ship. They will win if they sail away, and if you do not make it now, the gold will be lost forever.
Retrieve the gold to win
Your task in Wavetailer is to sneak onto the enemy ship, return the treasure and slip away unnoticed - do this to win. You will have to act quietly: the enemies are vigilant, and you cannot just pass them by. To win, look closely at the routes, pick the moment when they turn away, and take yours in Wavetailer.
Move with skill
There are locked doors and chests with Wavetailer gold on the ship. The keys to them are scattered in the most inaccessible places. If you try, you will find them. Explore the holds, pass by the enemies, collect the gold. Will you be able to take everything and get out in time, leaving the octopuses with nothing?
