Critical Mass is a great game that takes the Bejeweled/Connect 4 style game play of matching colours into 3 dimensions. The game is easy to play but very hard to master and has very simple but inviting visuals. The only major complaint I have is that it I can see it getting repetitive quite quickly. Definitely worth its low price and I will be recommending it to my friends. It also has a colour blind mode which is a good feature.
