Hello. Sorry to hear that. It is a simple html game and I already had quite some feedback from people who could play this release. Do you unzip completely the zip file and double click on the html file in the main folder (not the one in the figs folder) as I might have included a supplementary html file by mistake! I should correct these "wrong" html files in a fixed file. Thank you for your interest, hope you'll be able to play and that you'll enjoy the game!
Edit : I just corrected the file, it should be clearer now.
