Wow!
Well ... In this kind of music game, I have only tried the demo BeatSaber, provided with my Oculus Quest. And I still have not spent 30 euros for BeatSaber, despite all that can be found as ... "songs to slash" (French word game, I do not know how it goes in English) on BeastSaber, because that they are not my favorite music either. And, to make my own "songs to slash" (I reoffend), it seems that it is long and tedious. "Not glop!", As said a famous little French dog.
But the... With Boxmania.club ... I put one of my favorite MP3 files in the "songs" folder of my Quest (in the game, it appears after all those provided with it) and I did as in the Youtube video "boxmania.club - Create and test song pattern", and...
Wow! Instantly, as if I ... "danced" ... improvising, I created my "music to slash", which I could then... slash... immediately after. Difficult to make simpler, more efficient, faster and more fun!
My dear loxai, I'll take my hat off. In my opinion, do not stop.
That being said, I do not like the 1st theme (landscape) because the ground moves and it makes me want to throw up (motion sickness). Fortunately there is the 2nd theme, where only the boxes move. And it should simplify the direct access, in the game, to the player's personal music.
There might be other little things I could add (I only tried this game once and about an hour) but, frankly, for the most part, I repeat:
Wow!
