Sounds like its your connection and not itch.
I'm getting on average 36MB/sec through itch.
When I download through google drive, I can download almost anything instantly. 1 mb/s for Mega and 55mb/s for steam so I don't know why itch.io is the only site that behave this way
If you want, I can upload it to a google drive, email me at jamesdemondoggo2@.gmail.com so i can send the link because ill forgot to reply to this
No need anymore, I somehow fixed my router by beating it. Peak engineering
