1. Installation: The installer will close down if you do not allow it to install the flash player. That is a very bad thing considering the project has not been updated since 2009 and will have an old plugin. 2. The source code: The code is not available. 3. The browser based instructions: There is actually some good information in this tutorial game, but unfortunately, the over use of the program is limited due to it's requirement to install the outdated flash plugin.
