While I don't think Y-Faster 2 Fast is a fantastic hack overall, it certainly is interestig in how it delivers its experience.
YF2F is a funny little speedrun hack that turned out to be somewhat more than that simple label. It essentially - to oversimplify it incredibly - mashes together a handful of carefully curated Super Metroid hacks, and makes the experience frantic by adding a timer that kills you. The thing is, the rest of the hack is also designed to kill you, so you can't rush too much, because you will die. But that timer is always tick, tick, ticking down...
It's a quirky little hack, and it definitely takes it for best quickplay for me.

Meta once again knocks it out of the park once again with this second entry in the Y-Faster™ series. Do you have enough knowledge of how some classic (and not-so-classic) hacks work to make it through this in time?

In a true Y-Faster™ series tradition, the majority of the fun of this is trying out weird self-imposed boss orders. Real Gamers™ do the Redesygn™ area first. >:-]™

I heard you wanted Redesign in your non-Redesign hack, so I Redesigned the Redesign portion of the hack to include physics.

Another great entry in the Y-Faster series from Meta, this time with an amazing twist of paying homage to other hacks in a really cool way. These hacks are the definition of Quick Play.
