A downloadable astlan-2012 for Windows

Astlan is a gravity game for PC.

The gameplay is all about controlling a ship versus the inertia and gravity. The challenge of flying your way through the levels was made exciting and fun thanks to an physics & level design.

The fuel that powers the ship is limited, and the energy of the ship will go down on each collision. Dealing with the fuel consumption and the ship's life condition, the player must fly through 24 levels, avoid walls & traps, collect some special items and then land properly

Artistically speaking, the visuals are not meant to be ultra-realistic. A simple cartoonish color scheme was developed.
The game itself happens in a 2D play-field, and the visuals are all handled in 3D, offering a depth experience that make it more compelling but does not overwhelm the gameplay.

Great graphics. Controls a bit touchy for an old fellow (70 yrs).  What happened to Gamestart?  I have some of the betas still and was very interested back then. It just disappeared! Did it evolve into Harfang?  I also downloaded Mediecross. Great graphics there too.

Hi :)
Yep, part of the code of GameStart became HARFANG.
It's not the same engine, but it has some common concept and philosophy.

There was an idea (by me) to reboot ASTLAN using HARFANG, but, well, other plans came in the way :)

Maybe one day I will reboot this project.
