Hi! Check out my recently released game, that is a remake of an old game I used to play back then.
You control a ship, and you have to defeat attacking submarines by dropping bombs from your ship, however you have to time your attacks well to hit them. There are many variations of submarines that make the game challenging later on.
It features a custom OpenGL ES engine, supporting devices from Android 4.1 and up!

Please provide feedback, as it would be very valuable for further development.
