I really like the core concept here, having the music crescendo and add layers as the numbers go up is such a cool idea. It does get a bit tedious and a little dizzying at times, but it’s a great foundation and I could totally see this approach paired with more expansive visuals in the future.
The simplicity of this version is also really charming, though. The ramp-up hit a bit of a plateau for me; maybe speeding it up a little or adding some extra interaction beyond just waiting for the sap to rise (like a small click mechanic or mini-action) could help keep the engagement up. Overall, really neat idea and execution!
