This game is definitely a 5/5! It's clearly the work of a professional. The idea is awesome and fits the theme 'Everything is a resource' perfectly.
One small thing I noticed — it was sometimes difficult to place objects precisely on top of each other. I feel like adding camera controls, like right-click to rotate and scroll to zoom in/out, would make object placement much easier.
Overall, a FANTASTIC game. I also watched your devlog video — congratulations! You’re incredible. Keep up the amazing work!
