Best music game I've ever played, and being able to use your own music, and how the game reacts to the music which is pretty cool, Thank you Dev for making a great game!
Another amazing thing about this game is that I played my own made music, and at the very end of my song it ended up making a boss fight with a long block boss that took the side of the screen, it started shooting ton's of lasers, which would move up and down in a rhythm (or with the song), which I found pretty cool!
Another game that is related to this, is an Xbox game named: "Music Racer ultimate", (which is currently free) with music racer you can play your own music from a USB and the game will react to the song. Some following similarities to both of these games: Lots of flashing lights, Obstacles/Enemy's react to the beat and depending on the song the game will go other fast or slow.
But overall 100000000/100000000 Game!
