This time, i'm needing help with validating my code, like, i have all the coding stuff ready, it was working until now and it dosen't works anymore. I know this is bad explanation, but just shout me.
Hey! I need help! I have a game on itch and need someone to test the demo to see if it is actually available for people to play! Ty!
