For fans of Joss Whedon's so-good-the-Emmy's-basically-made-a-category-up-for-it "Doctor Horrible's Singalong Blog," the only way to improve the musical would be to make it longer. Aside from a few canon comic book story expansions via Dark Horse Comics, however, those who've been humming its soundtrack since 2008 will just have to enjoy the next best thing: a fan-made 8-bit adaptation.

Doctor Octoroc, the mind behind "8-Bit Jesus" and other projects, has taken commendable pains to recreate Neil Patrick Harris, Felicia Day and Nathan Fillion's performances a (viewable, but not playable) NES style video game complete with a chiptunes soundtrack, RPG orientation and cute item management integration. The pace is crisp, the music is spot-on and there's an overall attention to detail that could only have been programmed with love.

Act one is currently up in full, while acts two and three are reportedly in the works and should be out in a few weeks. I'll certainly be waiting.

Check out act one at Doctor Octoroc's official site or here after the jump.
