In a game about rhythm, the most important thing to get down is good sound design. VoodLoop definitely succeeds in this area. All the sounds are distinct and help the player in some way to understand when in the music their action will activate. In a lot of cases, the actions can even add to the music, and however unintentional this may have been, I found that the music would occasionally fit the abilities that I was holding with rests in the music where ability sounds could be heard and have more emphasis.
Something that I wasn't expecting though was the attention to player agency. In a game where the player's actions are fairly down to the timing of the music, there were still mechanics, such as the option to hold onto an ability and bring it with you until you wanted to use it with your cursor, that made me feel as though I wasn't just throwing myself at problems without having some sort of option in how to approach them. There were only a couple movement-based issues I could find in my playthrough, but overall, this is a very solid and enjoyable experience!
