If I want to know that this particular game is been made with unity or not?
Is there any way?
please help
You can just tell Seriously, you can see its Unity by looking at it in 9/10 cases.
On Android you can use an app like Smart Brain App detector (something like that) which tells you EXACTLY what is in your apps : Ad platforms, dev tools used, plugins, everything.
On PC you can probably right click the exe to find the info in Properties.
Heres an example
It also mentions unity and Mono when you look through the folders.
find the logs for the application and look for “Unity”.
eg, on android if you have the android sdk you could do:
adb logcat | grep -i unity
similarly for iOS, build the tool “deviceconsole” and do something like:
deviceconsole | grep -i unity
