+<p>The <code>dt</code> parameter specifies the length, in seconds, of a full movement step, and defaults to 0.1.
+The <code>dt</code> can  be anything and the game can still look the same.
+It is only when you change the <code>dt</code> without changing all the things in the movement step that are being multiplied by the first move argument that it will make a difference.
+If you lower the <code>dt</code>, everything will move faster than it did with it set higher, and vice-versa.

+<p><code>min_t</code> specifies the minimum time, in seconds, that has to accumulate before any move or show handlers are called, and defaults to 1 / 60.
+Having the <code>min_t</code> to 1 / 60 ensures that the controller can update the screen at a maximum of 60 times per second.
+A &quot;V-Sync&quot; such as this is necessary to prevent video &quot;tear&quot;, which occurs when the app is updating faster than the monitor can display.
