Play the Game!
To get the free trial from xbox.com, visit this link. The game will be downloaded to your Xbox 360 the next time you sign in to Xbox Live!
Once you have the trial game, you will be able to play the entire first chapter! The Indie Games service automatically ends your session after some time (currently eight minutes), however, the game will remember your progress through its auto-save feature. You can restart the game and continue playing until you finish the entire first chapter!
If you would like to purchase the full game, the trial game will offer you plenty of opportunities to do this for just 200 Microsoft Points ($2.50 USD). If you purchase the full game, you can continue right where you left off without downloading anything or restarting the game!
Have fun!
