It's popular Atari XE/XL game ported to Linux. The latest version is 0.57.

Screenshots:
Main startscreen	Robbo the robot is trying to get out of the planet. He must collect all parts of capsule to move to next level.
Robbo can be killed by many things of destruction...	The way is hard and dangerous...

Objects:

Wall - Very solid and unbreakable thing Normal box - Robbo remembers it well from the time of Sokoban. Pushing box - Once pushed it moves until meets another objects. Can blow bomb and kill an animal. Ground - Can be blowed or shooted Key - Opens the door Bomb - Very blowable thing, but can be pushed Door - Opens when you have the key Questionmark - Maybe it covers something? Life - Robbo loves it Capsule - Robbo's private wehicle Teleport - Moves Robbo from one place to another Screw - Robbo must collect them to repair capsule Bullets - A package of ammo Energetic barrier - can destroy everything it meets

Killing things: Magnet - If Robbo moves near this - he's killed Bear - Little, cute bear... Black bear - And it's older brother Bird - Very aggresive I think. Some kinds can shoot. Butterfly - Highly dangerous and precize. Can find Robbo fast and kill him. Kind of guns:       Guns - Some of them can move and even rotate Solid Guns - They use laser Blasters - Highly destructable. Bombs don't even have the time to blow up...

I also generated RPM package (Mandrake but should work on RH or PLD distributions) -
Debian package is available too (thanks to Krzysztof Krzyzaniak aka 'eloy')
