I created yesterday in the morning the project and worked there. I want to upload it to itch.io but it´s a 5,41 GB file. I have Google Drive for uploading it. I could try maybe something with Github/Bitbucket, but i haven´t much knowledge about it. I am very sure that this is my first project on Itch.io. So how should we do this?

Unfortunately you have to be able to upload it to itch.io for us to play it. Try contacting itch.io support and see if they can help you

Bro, that's crazy. How in the world did you come with a 5GB game? Just what made it so big? 3D models or HD audios?

How did it get so big in a day?!

lol, the prob was just that i forgot to package it. I  looked to the UE5 project folder
