Turn off the lights!

Here is a nice little puzzle game made using the grid framework. When you click a square that square and the four adjacent squares flip their color. Your task is to turn them all off.

The entire game uses only two scripts with a total of 70 lines of code. Sure, that may not seem like a small amount, but keep in mind that almost half of that is just whitespace and comments for better readability. The other half is mostly just to handle the user's input and only two lines are used for grid-based operations, i.e. finding out which tiles to flip. What's even better is that this works for any setup, you can even have holes and weird appendages like in the above picture. You could even move tiles during gameplay or generate the puzzle dynamically rather than by hand every time. Grid framework always finds the right tiles for you.

I will put up a video tutorial eventually once the package is released. I used delegates and events, so if you don't know what they are take a look at prime31studios' video tutorial:
