The game is a rehash of OOT with a few new gimmicks and a story centered on masks.

The issue with the game being nothing special other than a rehash by a fan (do researches, it's literally a fan game made before those become popular).

The game is barely interesting other than the new Ocarina gimmicks and the new Mask gimmicks.

I must say that it also has very innovative dungeons. That's pretty much all you need to know, in the end the game was kinda enjoyable, but it's really nothing special.

I would recommend you Ocarina Of Time instead.
