Play with the tile width
This tile board works by doing all the calculations as if the tiles were 1 pixel by 1 pixel. Each tile clone is given an x and y coordinate for their location on the screen grid, and the program places them on the screen based on that number, then multiplies that by the width of the tile. The Scrolling is based on a 0-1 scale, where 0 is 0, and 1 is the width of a tile. Then all these numbers are multiplied out by the tile width as well. This allows the program to deal with costumes and locations far more easily than by using the numbers on a full 64x64 scale. It's a bit glitchy RN but I'm working on it :)
