In terms of originality, this takes the cake. It is a delight to look at the game, and to see the animations and sounds so beautifully work with each other. The focus on sound design makes this game very pleasant.
However, in terms of gameplay, I feel even with the provided instructions, even more emphasis on certain sound queues or changing events could help. Camera 1 being the main camera and Camera 2 being Purple Toad makes sense, but Camera 3 being Orange Frog and Camera 5 being Green Frog should be switched, as that would make more sense visually to the player, seeing how they're lined up on the podium.
Also, revenue and rating goals I feel are a bit too high even on the "easy" level, so toning them down would provide a feeling of progression and learning in the game rather than just failing every time. All in all, I like the game a lot for its art and sound design, but gameplay wise it croaks.
