So fun!  The freedom that the stag beetle and frog gives maybe makes these puzzles easier than in your other games, but it's still really satisfying when you get the little guys in place.

I've played a bunch of your games in the last few days and I've only now realized that you not only make the music, but you PLAY the music on guitar and sax (and maybe other instruments) beyond what I presumed was just keyboard and/or software (which would by itself be impressive).  SO COOL!  

One thing you could think about is to have the victory guitar in the same key as the background music.  So when a puzzle is solved, you'd here a "fill" that meshes with the background song.  If the music and victory guitar are, in fact, in the same key...oops...nevermind lol!
