I'm mostly tone deaf, and so I wasn't able to fix the machine, but that's probably just me. Haha. Might be nice to ramp up the difficulty more slowly, like start with some single letter clues, and let the player have some success early on and get the hang of it. And I agree with some below comments that it was surprisingly hard to figure out how to get under the machine. Maybe have a persistent area at the bottom so there's a sense of what to click on, or another sticky note? I also was baffled by the switches on the fix screen. I spent a lot of time assuming those were related to the tones, only to find I couldn't flip them anymore, so the sensation I got was more of feeling confounded than "fun." But I really love the idea you have here, and I think with a little more onboarding even folks like me could have a great time. So I hope you'll take my feedback in a positive light! There's a lot of great ideas and creative thinking under this, and none of us had much time for playtesting. I appreciated that you put some on-screen clues. Thanks so much for sharing! Maybe something in my ramblings will be helpful. :D
