Pingus by Ingo Ruhnke is a free Lemmings-like game covered under the GNU GPL. It features currently 22 playable levels and runs under a wide variety of operating systems. Ported and maintained for the Pandora platform by Mr. Rob.

Release notes:

Hopefully fixed the “I don’t wanna write to vfat” issue that 0.7.5.1 ran into. Should work for ext{2,4} and vfat now.
