 - Ongoing code style enhancements (relatively new to C)
 - ~~Re-Implement rotation algorithm; my original algorithm was extremely buggy~~
   - Fix buggy S and T tetromino rotation
-- Empty rows that are full should "break"
-- Broken rows should cause other rows to shift down without losing ordering
