Liked it a lot! One thing that could be interesting to explore, should you continue to work on this: currently it feels like there is little reason for Gigi to be there, as she basically just works as a replacement for a cursor, indicating where you want to place things. The easiest thing would of course be to just cut her, but I think there is also a lot of potential to go in the opposite direction and instead expand on what the player character can do (e.g. active participation elements). Would love to see a fully featured factory game down the line!
