The Pirate Game is our (
Atomic-Gear) first Android Game, which started as a hobby project and is available for free. It's somewhat inspired by Crush the Castle and we decided to start with a simple game to gather game/unity3d development experience before trying on something bigger.
Due to the nature of the Unity3D engine, it will only run on newer ARMv7 based devices at all. Since there are also many cheap Android Devices who doesn't have good graphic capabilities, it may run slower there too during the physic simulation. But there is nothing we can't do about it yet, the physic is done by the Unity3D engine. We've done everything possible and added several options to reduce graphic quality for higher frame rates.
Recently we released a small content patch which adds 20 new level resulting in a total of 59 levels.
