Ah, I definitely tried to make it difficult, if not impossible, to solve later levels by just pushing the sliders to one end or the other. In the later levels there are also more complicated wave tables with very distinct intermediate shapes. But it was hard to know how many solutions a given level would have, not to mention the uncertainty added by the non-deterministic physics.
But it’s something for consider if I revisit this down the road. Thanks for taking the time to clarify!
