In support of UNICEF's efforts in Chile to rebuild the country following the terrible earthquakes and tsunami that struck earlier this year, Pablo Gorigoitía has drawn my attention to a persuasive game entitled Rebuild Chile, made to help raise funds. It's ad funded, so just click on the link to play the game and lend your support.
The game is a Pengo-esque sliding block game involving a digger and a helicopter. It has one of those super-annoying theme songs that you could perhaps describe as "catchy", if you wanted to be polite... thankfully you can mute it. Unlike other sliding block games, if you get into trouble you can use the helicopter to bail you out, reducing your score but often allowing you to avoid having to restart the level.
