I agree with you! Since I discovered Roccow, I’ve been using his songs for most of my games. It’s amazing, and he’s so underrated. (I forgot to give him credit for the music btw).
And the different ending is actually a good idea! The bird in the current ending is my real-life parrot, and even the sound is from him. But it would be funny to have something different for the hardcore mode, but, you know, the time limit was tough 😅
