Cool idea and definitely a game with potential 😄
I think a mini-map would help a lot, and maybe during building there could be some visual color indicators showing what needs to connect with what for the system to work properly.
At some point I think I accidentally broke my setup 😅 I had 3 barrels/tubes ready, but they stopped firing because something apparently wasn’t connected correctly, and I couldn’t really tell what the problem was.
But overall, very interesting concept 👍
