You should make the Guardian System Customizable, for example, when ever I play a game like beatsaber I always miss the note blocks because of the guardian system, if you can make it less distracting then that would awesome. Also Make Custom Menu’s because the Menu is just getting old and everyone is asking for it.
Beat Saber is a fixed location game - you stand still, right? So you can safely just draw the guardian perimeter way away from yourself all the way round, ignore the physical room constraints as long as it's big enough to take your wildest swings. Just don't forget and fire up a new game and go wandering into things!
