Thanks! I really enjoyed playing, it's a great game so far.
I noticed a bug where it doesn't let you get 100% on the Rehearsal. And at times, the notes are so close together and the "hit" box is so large, it feels like the song is playing itself. It'd be cool if there were special notes that had a shorter hit box so they could be placed closer together without removing the immersion, but that's just my two cents. With the exception of those two nitpicks, the game plays very well. Awesome work, hope to see a full version in the future!
