Ocarina of Time is one of the most beloved games of all time, and Nintendo gave it a 3DS remake a few years ago, but some ambitious fans look to take things in a different direction. Ocarina of Time 2D is a “demake,” taking Ocarina of Time and recreating it from scratch (using no pre-existing game engines) in 2D and in the graphical style of A Link to the Past.
This isn’t the first time someone has attempted something like this, but Ocarina of Time 2D appears to be progressing quite nicely and looks very promising. There’s a demo available for the game (which you can download here), as well as a trailer and videos (above) showcasing some of the features.
