Thanks for playing — and I really appreciate the thoughtful feedback! You’re absolutely right about level 2-2 — the visual match is correct, but the win condition was using a different check. Sorry for the confusion, and thanks for pointing it out.
As for hearing the waveforms — I did consider it, but decided not to include it as a core mechanic because I felt the resulting noise could disrupt the overall atmosphere. Still, it’s an interesting idea that might work well in another context!
