Good concept for a game mechanic
Some notes for if you decide to keep going with it:
- A little tutorial at the start would have been good
- I found it a little difficult to aim, though I have not hit beat saber in a while so maybe thats me .. lol
- When I hit them some changes in the music (which fits well by the way) would have been great
- A score or proficiency so I can see how well or badly I am playing
On the audio front look into audio stems with mixers to ramp up as the player is preforming well
Good job
