Very lovely game! I don't have much experience with rhythm games, but the execution feels nice in this one!
I think it would've been cool if there was a restart button, instead of having to wait for the game to end once I missed enough to know I lost.
Other than gameplay, another nice addition would have been to be able to choose different animals within the game. I kept getting the frog back to back when restarting, which initially led me to think it was the only one.
A very good game nonetheless! Great work!
