Really awesome work! while it is a bit under-decorated graphics/audio wise (for a nes game) it's still really good and is an amazing example of what things translate well in a non 2D medium...like the intro for example...without 3D and first person this part is a bit underwhelming...but the core parts of the game still work out and I'd even say some parts are a bit more intuitive than in the original...
really interesting project and I'm glad to see all of the updates...It shows that you actually give a shit about your work here!
