Barbarian Onslaught - The Secret of Steel is now updated to a newer version. This update includes few bug fixes and gameplay tweaks. You can now drop enemies that you have picked up by pressing the down key. This is already in the Author Comments.

To be able to play this updated version you have to reload BO:Secret of Steel. You'll be sure you're playing the updated version if you see the dark-gray text "v1.1" in the bottom-right corner of the loading screen (Dark-Gray Text, might be hard to see!).

You will be able to continue playing from your old game-progress.

What I can't say is how you should be able to reload BO:Secret of Steel without removing your internet-history and your old game-progress in the process. =(
