Well done! I can see myself get pulled into this game after few tweaks. As others have mentioned a tutorial would be nice, I was trying to buy more stuff but couldn't place it so I thought you can have only one active part at all times.

There's definitely a bunch of UI feedback missing, dimming thing/disabling them and telling you you don't have enough to pay for them is one of them. Your comment made me realize that the factory can actually become full and if you build something at that point you'll probably get stuck in "placement mode" too.
Thanks for playing!
