So we got some play-testing done by the amazing jbarrios from TIGForums (You can join in and send your own feedback as well at https://forums.tigsource.com/index.php?topic=69755.0)

Some of the issues that have been addressed:
* Resolution - It is now possible to change the resolution of the game! AstroDucks now comes with a launcher where you can make a bunch of settings before running the game
* Controls - a new control scheme has been introduced which allows the user to use mouse and keyboard - would love to get feedback on that!
* Information - dialogs have been added to the first stage, explaining some of the basics of the game.

All of these improvements are in the new demo - check it out and let us know what you think!
