This year game I worked on for the Sydney GameJam. The game was created within 48 hours and at its core with 2-3 people. The starting team consisted of 3 people: Me and my co worker (also a developer) Derek and a female artist Jane. Later on we got some help from a few other individuals including a Music Composer by the name Angus as well as a CG and a panting artist by the name Hanjin.
I wrote the 3D sprite engine, the path smoothing, AI and animations (sine curve rhythmic motion + some smooth & natural character movement). Derek wrote the initial A star pathfinding, the whole sound and music blending (7 layers of music are blended dynamically), the collision map management / generation and the enemy waves pattern generation.
It was a good coding experience as booth me and Derek and to code simultaneously via SVN on the same code base often touching classes on the same time. Obviously the code became very unstructured and messy :) but it worked really well for the short time we had.
