Alwa's Awakening: The 8-Bit Edition is an official NES demake of the PC game Alwa's Awakening that was co-developed by the developers of the original game. While Alwa's Awakening was a throwback to the 8-bit era of video games with its retro-esque gameplay and graphics, the NES version is a full-on port to an 8-bit video game console. And unlike most demakes, this version retains most of the levels of the PC version along with adding exclusive content.
Darkman425 forgoes the use of screen wrapping and out of bounds glitches in this run that would save over 20 minutes of game time in favor of playing the the game mostly inbounds. Other glitches are still used to save time along with soft resets. You can read the author's notes for more details.
Watch this run being played back on a real console.
