This Game has Gameplay a la God of War and others that came after and i really missed such Games, as everything nowadays is going the "Souls" Way.
The Demo showed that the Game isn't as polished, but it is fun and has nice Graphics, i am looking forward to get full full Version.
So from what i can say:
Graphics nice, it delivers the Pirate Theme very good and is appealing.
The Gameplay was also nice, you can take Guns from killed Enemies and also take other Stuff laying around to hit your Enemies.
Besides your weak and hard Hit, you have a AoE that stuns Enemies for a little Time and a Gun to shoots once here and there.
For your additional Defense you can block and roll around.
You can grap Enemies and do a FInish Him Move, for heavier Enemies, you have to weaken them first.
