I don't think you did the mobile version right. It's not supposed to be a zip file, but an apk file. Unzipping it doesn't yield the apk file either, from what I can see in it.
Apologies I wasn't quite specific enough, It's not actually an APK, I'm considering speaking with a sideloading company for an actual side game, but it should now support in browser html play for mobile devices, specifically should be fine for default safari for iphones and Ipad, as well as a good chunk of mobile web broswers, tho sadly I don't think I can get the android build to work, so while it will be playable from web there, I don't think I can get it to be app ready
