The project is 2.7 GB I believe. Been a while since I've transferred it somewhere. Last time I tried I contacted itch.io support and then told me - no. Basically told me to re-do my project to get it smaller.. hahaha
I tried to explain that my project couldn't get any smaller because it is a Game Book. You know.. a bunch of different endings to the story type thing (Chose Your Own Adventure) but with doors and clouds in it. Kind of hard to explain to tech support.
