Well i have tried the joiplay and extracting unzipping files and joiplay just tells me the folders i just unzipped are empty. I tried reading the readme files but those dont comvert to readable files no matter what programs i try to use google just shrugs its shoulders at me even though it says it could read them if i uploaded them to my google drive but they never convert correctly so yeah again this is harder to do than just making an apk i would imagine since i watched a guy create a game in like 10 minutes and upload it to the playstore with a windows and amdroid version.
But then again im not a computer programmer. So i have no idea how to make this game work at all since the files i downloaded didnt seem to have an exe file anywhere in the 2800 or so files. Joiplay tells me every file is empty and im just giving up on it. Im sure its a fine windows game but i would suggest removing the android tag as you lack a direct apk file to make it work on android directly
