A great non-violent 3D arcade: The submarine life is too risky even for the fearless reptile. 40 brilliant arenas and 4 mysterious worlds lie ahead of our hero. Great music, sound effects and Matrix-like camera movements make 3D Snake Arena the game for all ages. At the same time like in all puzzle games you'll have to be smart throughout the entire game - as one wrong move and you'll find yourself stuck with nowhere to go. Good luck!

The Commander decided that a special training facility was needed to
provide an elite corps of pilots for the advanced military units used
in colonization and reconnaissance work. The Academy for Advanced
Pilots was founded in 2813 to meet this requirement.
With an intake of over a hundred would be pilots a year, only a few
meet the requirement of skills. In order to graduate from the Citadel
cadets must complete 180 missions...

A sokoban game - you must move a cosmic sphere around a game board in outer space moving star blocks. It's trickier than it sounds and with 375 other bizarrely shaped levels, it gets trickier still. You'll need to be at least one step ahead of yourself throughout the game, as one wrong move and you'll find yourself stuck.
Great 3D graphics run fast even on weak machines.
Like all great puzzle games, it's easy to learn but difficult to master.
