Post-Mortem
Libra offered a great learning experience for understanding 2D corrective physics. Libra was the first procedural map generation that I’ve done. As a first attempt at it, I’m relatively pleased, but knowing the tools I do now, I could do something more interesting. The most fun I had with the game was making the flamethrower and utilizing additive blending to get the white hot fire at the center of the flame.
