This is a nice little game. On the whole it feels like it occupies well-worn territory--part of that indie puzzle platformer trend of the 2010s, but that's not the worst thing in the world. I think the middle of the game drags a bit but that might be personal preference. The singing mechanic could probably have been implemented in a more central or interesting way. But holy cow, the end of the game really just pulls everything together. Emotionally powerful and catchy, the ending will pull feelings out of you that you didn't know you had for the game. In the end it kind of harmonized and achieved something greater than it's constituent parts. It's worth a little playthrough; do not buy it on Switch.
