@nolttr21, the images are smaller when in the tray; they become normal size when in the placement area. This was done to reduce the size of the tray (which would need to be around two to three times the size of the rectangle, otherwise).

@Heet_Patel, you can start anywhere and end anywhere. No location is inaccessible from any other location. The green dots are just "tracers" used in building the maze. They hold information for a location until that location is confirmed to accessible in the final production of the maze.
