Since my rather mediocre attempt at making a space invader game I stumbled on a cache of Visual Basic for Applications games written by Japanese excel wizards. I have even someone create Zelda?!? What an inspiration! Making complete, beautiful, fun arcade / gameboy style games inside of an excel spreadsheet is possible.



This is my first crack at recreating the old game Snake. Advice please!

      Since my rather mediocre attempt at making a space invader game I stumbled on a cache of Visual Basic for Applications games written by Japanese excel wizards. I have even someone create Zelda?!? What an inspiration! Making complete, beautiful, fun arcade / gameboy style games inside of an excel spreadsheet is possible.



      This is my first crack at recreating the old game Snake. Advice please!
