Diver is the physics driven Silverlight game I've been working on for the last few months.
The game is a work in progress but I decided to release a playable alpha version to get feedback and to show what's possible with the Silverlight framework.
You control Diver using only the mouse. The position of the mouse on the screen maps to Diver's posture. Simple mouse gestures can be used to make Diver perform various actions.
The first three Dive's of the game are designed to teach the basics.
A word of warning, the game will probably seem pretty difficult at first but I think you will find the control mechanic very rewarding after some practice.
Have fun and let me know what you think.

Note: A few people have recieved some exceptions on the last two levels. Please let me know if you have any similar issues. You can either post a comment here or use the feedback button at the bottom of the game page. Thanks.
