update 1.1

*Fixes a rendering issue affecting various screen sizes.
*The bigger black squares, now have smooth "rounded corners".
*Added a new feature in which when a wrong colour is clicked, that colour gets highlighted with red a red border instead of the usual black. This can be useful if the phone is set to silent.
*Improves overall performance, and reduces the amount of lag. (The buttons can be clicked on at a much faster rate)
