Strictly speaking, a copy of BeatSaber.
I fear that there will be legal problems (copyright infringement).
The Differences:
The lightsabers in this game are a bit shorter.
The cubes further apart, you have to make more sweeping movements.
Unfortunately only two songs.
Unfortunately only one level of difficulty.
Unfortunately no online highscore list.
With more songs, online highscore and difficulty settings, this game would be a clear buy recommendation for all BeatSaber addicts. :)
But please do not sell via Steam or Oculus,
as these platforms lock out their paying customers with forced updates.
I will no longer buy games on these two platforms.
Good luck with SlashMusic
