Thom has released a new little touch screen puzzle based upon the picking demo found in the libnds examples.

Press A to start, then touch groups of shapes as they whizz around the screen. Select three of the same type to make them go away. Remove all shapes to move up a level. Game ends when time runs out.

Release notes:

I’ve uploaded a new version with better spacing and a better view of the objects. The picking in this version seems more or less spot on. I’ve also added a really annoying sound for good measure. ;D
