I tried it in opera but still not popping up.
Please make it downloadable so it can work well through Joiplay
I uploaded a download link, if it still doesn't load for you try using chrome when you run the game
I originally used cbrome it didn't really worked and can you try putting the images that you used in that zip file? Cause it didn't work in Joiplay.... mostly playing in Joiplay would fix that problem
