Thanks for your feedback.
This game is free and always will be. I do not set the task of making money on it.
For me, the goal was to find out how quickly I can create a copy of the "beatsaber" alone.
It took me about two weeks to create this game. Yes, it is far from perfect, but I plan to modify it. And maybe I'll take some mechanics out of this game for my future original games.
One of the points that I emphasized in this game is the creation of an editor that will help all users to easily add their tracks to the game. Users can add three difficulty levels for each track.
