In the last few days, I implemented head-bobbing and "chunk overrides", which basically preempts the procedural generation of certain chunks to insert author or player created bricks and other items. Took a big chunk of time to do so, but it serves as a basis for level design and a save system.
My goal for today is to create the save/load scripts. In addition, I need a new function that pushes players after a moving brick hits them. If I have time, I'll begin working on the ability to vault up to and over ledges.
