Hopefully this project will neither become abandoned, like a couple of attempts before it, nor shut down by Nintendo. The Legend of Zelda: OoT2D is an unofficial, fan-made game for the PC that takes the story and design of Ocarina of Time and builds it around A Link to the Past's artistic design. The most interesting part, for me, is how they will redesign the puzzles and dungeons into a different basis. I would like to compare all three games, Ocarina of Time, A Link to the Past, and the fan-made 2D OoT remake.
The team built their own engine for this game. To preserve the pixelation, you can use the escape key to select from one of four sizes that prevent art pixels from being spilled between physical ones, creating a blur. The UX is a bit counter-intuitive, but they offer a lot of the customization that PC gamers would love.
The game is not done yet, but a demo is provided. I tried it. It works.
