This is to show the generation system of the Super Mario Land recreation I'm going to make. Why did I share this so early? Because there is a bug where some tiles at certain points will disobeys the camera's rules and drifts off into the distance. I tried everything I could think of, but nothing worked. If you bother to read this, look inside the project and see if you can help find the bug.
