Ahoy, Sailors!
There is and important message for players froom countries where Sink Again was not allowed to purchase.
Right after the release I've got many messages from people of different countries like Australia, Poland, Canada, Japan and others, that they do not see the price and purchase button.
It was my fault, I though Steam will automaticly generate prices to all currency but I was wrong. I fixed this issue couple days ago but had to wait for Steam to check the prices.
Now everything should be okay. Price for all other currencies are set.
All aboard! Play the game and have fun!
