Played the free version. Girls disappear in lockers. removing lockers seems to have no purpose or bonus but you give players the option. Game crashes randomly. You need to fix your game. Looking at it there doesnt seem to be anything heavy enough to cause a crash. even if the newer versions are better there is no way of knowing that from your demo. Starting to think this is a Unity thing. Ive been seeing a lot of simple Unity games subject to crasshing.
