Love the visual style, reminds me of the I Spy books. Sometimes it felt a little hard to know which lights were out without quickly scanning over all the pedals, and I think that was giving me a bit of lag with the mouse. And (as others may have said) how to turn a knob with a mouse click-drag is a little ambiguous (though, this game could be rad as hell in VR!). Maybe display it as sliders instead? Seems like it might be a slider behind the scenes.
I would love to know how you designed and programmed the sound for this. When a value knob is off, is it that track’s pitch and/or tempo shifted or something? Or is it playing an entirely different “wrong” track? Very cool interpretation of the theme!
