But do you know what's better than a triple jump? A quadruple jump. In mid-air.
1,2,3 is a game that's all about jumping, and collecting three boxes in numerical order. That's it. Why is it so compelling? Well it's got that Super Meat Boy thing of being mind-numbingly difficult, but not unfairly so, meaning that you continue to traverse the learning curve until you succeed. The last two levels are particularly tough.
We enjoyed it. Worth remembering that the game was made in 48 hours for a competition though!
