Ok dude, this is yet to be a huge help for me...Yes, I have been having the same problem as everyone else that chats in this general discussionpage...but when i click you link for "itch app" it doesn't come up with anything but all it says is 404 not found with a pic of an orange skeleton...or...how can i update the game manually...because I didn't pay for it, my friends friend had it from itch.io and he gave it to his friend who is my friend and my friend gave the USB to me so I could download it for myself without paying the price. my friend who gave me the game from USB tells me to be patient because eventually the game will update itself after some period of time after the updates release to the general public.

Apologies, I’ve shared the wrong link. I’ve fixed it now, so it points to the Itch app.
As for updating a game that you don’t own on Itch.io, I’m not sure how anyone can help there. You can either purchase it and get all future updates, or check with the original developer, to see if the game can update itself.
