Can you get WolfQuest without downloading it?

You cannot play WolfQuest without first downloading and installing it. Unlike most other Unity games (Fly Like a Bird being a good example), WolfQuest can't be played in Unity Web Player for two good reasons.

1. The sheer filesize of the game will mean long loading times.
2. The game was never intended to be a Unity Web Player game. That being said, the developers will not change this nor will they be updating the game as of December 2012.

That only leaves you with the option of downloading the game and installing. If you have any problems with the installation (such as a disk.cab error) you will need to delete the installer and try again.
