Thanks for the feedback, YouCarryOats! I agree the sound is currently annoying. I think decreasing its volume and choosing a nicer pitch will help keeping it in the game. Thanks for silencing your computer instead of giving up the game!
Yeah, I got the color feedback, and I did improve the color differentiation between the Ultra and Classic jams, but I guess I have to work more on that. Perhaps you could provide some interesting ideas on this matter. Would you mind talking about it at some point?
