Playing McPixel is pretty much like being drunk. Everything seems like a good idea.
The wild gameplay, that awards not only the correct solutions but also failed attempts, requires a great deal of creativity. Creativity - not just random clicking on every single pixel on your screeen, as many have pointed out in their reviews. After a time, the game begins to draw you towards its twisted logic. The bumpy run you had the first time playing McPixel, turns out to be very addictive, definately re-playable and captivating long ride.
The humour used by the creators is a little bit foul, sure. You will feel it pays tribute to your inner 14-year-old. It fits, however, the randomness and roughness of the game, making you smirk at the most obscure gags. (And is still better than American Pie.) What is even more exciting, the game has been provided with themed levels, for example paying tribute to other famous video games.
Also, lots of explosions.
