Use the arrow keys to move around (no WASD). This is just an engine you can use to make scrolling backgrounds. I am aware that the tiles either disappear too late or stay shown for too long. You can easily fix that with some creative Showing/Hiding.
Effective X and Effective Y show your position on a Cartesian coordinate plane, given that the red dot in the middle is (0, 0), rounded to the nearest whole number. This can be useful if you want to make a game around this. If you do decide to use this in your project, credit would be greatly appreciated.
