I'm not sure what's up, I bought the pack years back, but now when I try to download it, instead of downloading the asset pack as folders and pictures, I get a unity WebGL document that opens to a blank grey square.
i just rearranged it so the PixelMob.zip is before the PixelMobBuild.zip in the files? please let me know if it works now? you can also access downloads from the "my library" link in top right menu drop down. otherwise i can maybe email it to you while i figure it out
download PixelMob.zip instead of PixelMobBuild.zip that is the one that plays in the browser here
