Serendipity (Michael Gavrilo)

Serendipity is a minimalist puzzle game - press the buttons surrounding the board to switch the colour of an entire line, column or diagonal. The objective is to turn all the squares to the same colour (any colour). Originally made as a participant to the Black and White Jam with the theme "sticking together" - but with the conscious decision of including the ROYGBIV as accent and other colours after level 100.
