Actually we did it in 2 days (that includes sleeping and having some fun time)

We didn't create it all from scratch. We used our old PGD compo entry for multiplexity. http://www.pascalgamedevelopment.com...er=asc&start=0
However we did a lot of programming to get to this point.
The only things that where untouched are the controls and physics.

Things that where added:
Sounds (2, but we have sound )
Music (2 sounds tracks)
AI, not optimal, but they follow you and try to hit you
Weapons (currently 1, we spend also some time on homing rockets, but they didn't made it to the deadline)
Hit particles
Menu
A whole new level
Level borders, when you go out you just explode... (bad thing actually)
New graphics for the plane
A new plane that didn't make it into the game also... maybe next time...
