I'm sorry you are having trouble. Depending on your computer's security settings, you may not be able to run the macro and play the game. You should be able to "Enable macros" via a message bar at the top of the screen when you start Excel. However, if you don't see it and you have appropriate permissions to change Excel security settings, you can go to the File - Options menu and then clicking the "Trust Center" on the left. After clicking on the "Trust Center Settings" options, you will get the option under the "Message Bar" side menu to show a message when macros are blocked. Restarting the Excel workbook should now show you a message that the macros are blocked but you should be able to enable them.
If this doesn't work for you, I am sorry you were not able to try my game, but thank you for trying to play it!
