Simple and elegant puzzle game. The music is charming, maybe the background and colors needs a little more sparkling.
Congrats on making so many puzzles! I haven't tried the Masters of Balance one yet.
It is a little uneasy that the jauges only go in one direction, so you have to look at the board to understand which side it's tilting. You put the rotation sliders just below these jauges but I dont really think they relate (jauges are a gameplay indication, while sliders are visual settings). The fact that you loose when there's too much imbalance from both axis, instead of the maximum imbalance from one axis isn't easily readable from the jauges neither.
Good brain exercise though, well done making it 100% native JS:
