Ah I worried that would happen. I tried changing the frequency range a bit but I ran into issues where the lows were way too low, the highs were way too high (and more headache inducing than they are now), or all of the frequencies were too close together to be able to differentiate them. If only I were a sound engineer haha.
Thanks for playing though! Glad you liked it! "Nearly perfect" is way better than I would have hoped for.
