That was super cool! I liked that it was half factory builder and half alchemy game and it blended the two seamlessly. I also like the "scaling" system where the game literally goes "cool design, let's see if it scales." It was kind of nice to setup a good system and then just kick my feet up and watch the cash roll in.
If you're doing a post-jam build I'd love some QoL user experience stuff like being able to select and move buildings, copy-paste, etc.
Really awesome submission, my favorite I've played so far!
