Unfortunately, we don't have any plans of making a browser version of the game at this time. Though we hate disappointing our fans, we simply don't have the time or experience needed to comfortably port the game to browser right now. If you can't download the PC/Mac version of the game, perhaps you could download it on Android or iPhone, whichever you have? Alternatively, you could try watching one of the many playthroughs of NMF on Youtube if all else fails.
