Thanks so much for the kind words and thoughtful feedback.
You're right - the belt overflowing is actually part of the intended challenge. The idea is that the output machines are intentionally slower than the input, so you have to stay on your toes and keep the flow under control as best you can.
I totally agree that it’s not always clear which items need to be color-coded and which should be swept away. That’s definitely something I’ll i should improve.
Really glad you enjoyed the concept and theme - thanks again for playing and taking the time to leave feedback.
