I'm so glad to hear you enjoyed the silly upgrade animation - it was actually an accident. When you clicked to remove a triangle, I needed him to lean over the conveyor belt to kick it off, but then that animation still triggered if you clicked above him too. I left it in because it looked funny, and then when I added the upgrade buttons, it worked out perfectly lol
Multi conveyor mode is a great idea, I'll add it to the list! Was there anything else? I love some good bossa nova music too
