Hey man! Great game guys! I like what you guys build there, especially since I really like tycoon games. I wanted to do one too for this game jam, but I thought it would be maybe a bit too much work. I ended up making a coffee making simulator thing, you may want to check it out: https://yapsinho.itch.io/the-perfect-coffee
Feedback for your game: I figured out that you can rotate things with R in the comments. Definitly add that somewhere, since it is intuitive in a game, but you can never know what features are implemented in a game jam.
I really like the transition between build and customer mode. In general I think this game would look super nice in polished graphics!
I think you did a really nice job in building around your core and I can see definitly see potential in this to be something pretty awesome of you continue it!
