Thanks a lot! Glad you noticed the layering of the drum and animal sounds.
You've made some really valid points about some of the shortcomings of the current version of the game. Solving the problem of the beats being out of time when looped is tricky without a metronome to guide the player but I think it's doable. Clearer visual guides for the expected inputs on the 'piano roll' is definitely doable and should be improved!
