Super Mario World 2: Yoshi's Island is a vibrant, colorful and fun game that stars the popular Yoshi. From a technical standpoint, the game is very exceptional on the SNES due to its use of the SuperFX chip, which allows for many cool special effects that are otherwise impossible on the SNES.
This movie by Carl_Sagan (no, not that Carl Sagan) is fast-paced, action-packed, and full of entertaining tricks and maneuvers. In other words, the very essence we tool-assisted speedrun makers enjoy. It also improves the previous run of this game by over 5 minutes. For more details, we recommend reading the author's comments; there's a lot more to this movie than meets the eye.
