so i downloaded the clangen and i have a file named clangen but how do i open it?
you'll get a 'zip' folder which looks like a zipped up folder, right click and click 'extract all' from the drop down menu, then extract it into the empty clangen folder. If you have an antivirus, turn it off temporarily and then search 'clangen.exe' from within the folder, and double click the result it gives you (it should be a warrior cats logo but sometimes it has a little blue box icon instead, it's the same thing). Hit 'run' on the pop-up after you open it. Sometimes you get a malware warning, but hit 'run anyway'. The warning only happens because the game uses .exe files and most downloadable nowadays don't use .exe.
I suggest making a shortcut on your desktop screen if you don't want to find it in the folder every time you open it.
