This is a super clever idea! I legitimately laughed out loud the first time I mined IRONY. I think my favorite part though was the sound and feel of everything, it's super satisfying to place lines of conveyer belts and I love the rhythm the sfx make with multiple lines all feeding the hub at once.
I think some simple UI queues would help a lot, it took me a minute to realize there was more game area than the space I started in, and it took me a minute more to find the hub. I also kept trying to click items in my hotbar and ended up placing conveyers underneath it.
