--Braid creator Jonathan Blow explains how he built and implemented Braid's time-rewind mechanic in this video from GDC 2010, courtesy of GDC Vault. In Braid, the player can rewind time at will -- the scene plays backward at an accelerated pace, like you might see on a VCR. Blow explains in detail how he programmed and designed this mechanic, why he chose this particular method instead of other possible solutions, and how he dealt with many implementation concerns.
