Hi everyone, I am trying to build my own portfolio; at now I just  uploaded very few games(some prototypes), I am getting some obstacles to upload a solution greater than 1 Gb. How could I solving this problem?I look forward to hearing from you.

For larger uploads you need to message itch io directly for approval.

You could also compress the files in a zip. Or go through your game and reduce the textures by limiting their render sizes, I did this with my game, I managed to get my demo down from 1.19GB to 700 - 800mb.
