I know that the itch app will show you this message if you try to download the game. You can't download this game through the itch app, it's too large. Use a regular web browser instead! Opera GX will do.
thank you really much
i am sorry to disrupt you guys again but what should I do next when I have the file now (from google driver)
It's a zip file, first you unpack it, then you run the Eternum.exe file inside.
