Cannon is a 2D trajectory simulation/game. The basic objective is to adjust your angle and power in order to hit a target.
Version 2 recreates Cannon from the ground up using the AndEngine open source 2D game engine.
As of 2014-03-15, Cannon is now open source under the Apache License!
The touch screen controls use pressure sensitivity that will likely need adjusted for your device. It is in the Scale preferences screen. Move your finger with a soft touch to adjust angle and power, press harder to fire.
Too slow/boring? Increase the speed multiplier, also in Scale preferences.
Random Targets: Targets are placed randomly on the screen and you try to hit them to gain points. With both Collision and Keep Targets options enabled, as is the default, it becomes a real challenge as old targets become obstacles.
Custom: Create your own target via screen coordinates and change a variety of variables to try hitting it.
Internet & read phone state are required by ads.
Prevent phone from sleeping is requested by AndEngine.

The issue tracker, which can also be used for suggestions, is at http://tracker.pilot51.com. Though it should be noted that Cannon has been mothballed due to too many negative/unconstructive comments and most of my other apps doing much better and consuming my time.
