Loved the pun title. Very cute dinos. The tutorial was slightly hard to follow as the little meteor moved around with the text and I moved around and he moved with me and it was a bit of a mess, but I got it.
At first I wasn't sure how I was supposed to know if the note was correct, as I would make the meteor play it, but it'd give me no inditcation on if it belonged to the scale or not. Thankfully, I noticed that at the top of the screen it gave me which notes were supposed to be flat or sharp or just normal. It also helped that I know how to read music like that as opposed to with the letters.
The music itself was cute. I'm not sure if it built up over time thanks to me collecting notes or if just kept going by itself with no changes (pretty sure it was the latter). In any case, nice game
