While waiting for the approval of my second game (3 Coins At School) on steam (It took over 4 months), I have worked on another game called GalleonMate:
GalleonMate is a free to play game where you and your mate will control a Galleon, and fight against other 15 galleons controlled by other 30 players.
The 2 players on the galleon needs to choose smartly if take position on a cannon or drive the galleon to avoid enemy shots or get closer to your opponents.
Game servers can also be rented directly from your account, you will be able to upload your custom map made with the map editor provided in the game folder.
The game has been released a couple of days ago so it's main problem now is that there are almost no players, I am trying to advertise it but will take time.
More info can be found on:
https://www.galleonmate.com
There you will find also a download link to play the game (Windows only as is made in DBPro)
