Thanks! For the music, the first level is very calm/orchestral on purpose. The next level music gets a bit more chaotic, and as levels progress and the bear finds themself in more crazy situations, the music will build until it is very crazy. But I do agree with you to an extent.
Thanks for testing on a 144 hz monitor!! Yes the jitter is something I'm aware of, I need to implement fixed timestep interpolation better so different draw rates work well. I appreciate the feedback.
