When I first saw this game on Reddit I thought it would be a bad version of Beat Saber or Audioshield.
It takes inspiration from similar games but had its own unique innovations.
-Multiple weapons
The game automatically switches you between shields, swords, arm cannons, and a bow. Each has their own mechanics for interacting with notes.
The shield isn't a simple block like Audioshield if you simply block the note just pops but if you punch into the note it will be volleyed back to the boss and if it hits it you get a nice chunk of points.
The swords work the same as Beat saber although there is some mechanic where Zelda style swipe blasts come out of your sword and track the boss hitting it for points (I currently do not know what triggers it)
The Arm cannons are simply timed shots where the targets appear, and if the boss is at the target you get extra points. I am unaware of anything else for that.
The Bow is currently the "weakest" of the weapons and will hopefully see some real TLC. The interesting part is you use an arrow hand to catch a bullet from the boss which turns into an arrow for your bow and a timed shot similar to the arm cannons show up to launch the arrow at with the bow.

-Ingame editor
I absolutely love the ingame editor, I've spent hours making songs in the Beat Saber editor and it is so refreshing to be able to seamlessly go from recording a song to playing it. Although you better have the song memorized as you have to record the song in one go.
You can freely switch between the 4 weapons and even mix some of them together (Sword right hand Shield left) and when you or someone plays your recorded beatmap the game will equip the right weapons at the right times.

-360 play
All the other similar games have a stage or rails in front of you and the notes come towards you down a line. in DtB the boss has the ability to move 360 degrees around the player and you are able to record your beatmaps in full 360. Have notes do a full spin around the player or require them to catch an arrow and quickly shoot it behind them.

I am excited to see where this game goes as it is developed and I very much recommend it if you enjoy these kinds of music games.
TLDR Not a ripoff, not a clone, unique ideas.

Hey, flying fire

The glitch is back where the beat monster isnt doing anything pls fix,
but its a bit different because recording songs works fine just playing any of them (even the tutorial ones) dont work


(I'm always editing this review if i see any bug or glitch so if there is any glitch or bug i am editing this review)
