Super Mario World is a game which needs no introduction.
This movie beats the previous SMW movie by a mere 3 seconds. Strategically, this is very similar to the previous movie, but a new technique which involves keeping flight status through doors and pipes saved the majority of the time. This game is now extremely tightly optimized to minimize lag between levels.
This movie is a joint venture between Fabian and JXQ, but small and big optimizations were contributed by several people: skamastaG, thegreginator, mrz, jimsfriend, Flagitious and Arne_the_great.
