Game Project 1: Fruit Knight
This was the first game project we did at Future Games. Our group was a team of 6 people, 3 programmers and 3 2D artists.
Project 1: Fruit Knight
On this project I worked on the "boos", or in this case the skeletons. The project lasted for a little less than 2 weeks. It was quite intresting since I had never done AI such as this. The only game I had made prior to this is a simple platformer with "AI" only moving back and forth between 2 walls.
