Future features

The following updates and revisions are being planned:

* Change ant movement to stop and start in a cycle.  This will result in a major change in the gameplay mechanics.  It will allow the user to move the cannon across the 16:9 widescreen before all the ants progress to the threshold line.

* Add sound effects and possibly music

* Clean up the main menu's appearance and interface

* Add input support for touch, mouse, joypad in additional to existing keyboard-only input
