There have been six Gosu entries for the last Ludum Dare 48h gamedev compo, and the scores weren't too bad either, so here's the list of links to the respective final blog postings:

Walla Zombies by ChadyG (Ruby, OS X) and a version that is easier to run on Windows

Evacuation by jsb (Ruby, Windows only)

Escape from CERN by mathias (C++, Win/source)

Defend Your Castle by pythong (Ruby, Win/OS X/source)

Solar Lift by codekitchen (Ruby, Win/OS X/source)

StarFerret 48h by me (C++, Win/OS X/source)

I am probably abroad next time (August), but hope that everyone else will do just as crazy entries again :)

Jlnr are the buildings 3d? or is it some openGL trickery

I need to start learning openGL i think.

I didn't want to touch OpenGL in a competition, so I just took the four corners of the building on the ground, multiplied their distances to the screen center by 1.1, and then connected the resulting 8 points using Image#draw_as_quad (or Image.getData().draw() in C++).

The fake 3D look when the player's fighter moves is another story… :D

laying in bed last night I thought that it might be done that way :)

I asumed that the ship was just a 3D render using blender, milkshape or somthing

The ship is composed of two images (ship body/cockpit) that I draw at an angle and with a varying factorX, and most importantly, with a small offset. Faking 3D is too much fun, but a blender render would of course have looked better. (Shading, proper perspective)

Wow that was another story.

Fake 3d has got me hooked. checking out that Wolfenstien clone has definitely caught my eye on Ray-casting, honestly didn't think it would work so well.

nice voice work btw ;)
