It's very cute and complete presentation-wise, and the idea is interesting. However, to be able to apply any strategy, the player is somewhat required to learn the synergies between the different types of buildings. In the end, as there is a strong randomness component to building placement regardless, player agency gets nerfed at the point of execution anyway.
Personally, I only skimmed through the synergies and types of buildings and then started experimenting. After a few rounds, I found that the score would typically range between high 60s to low 80s, and whether or not I tried to be deliberate or just randomly placed them seemed to have little impact ultimately.
To call it what it is, it's an interesting little experiment, and the polish is very complete. I could be wrong, but I think you made this with more of an intention to explore odd gameplay avenues rather than with the goal of making it fun. The polish and consistent "flavor" of the game's tone does help sustain player attention on it for a while, despite the disconnect between player choices and actual agency (which is a consequence of the jam theme).
Perhaps a higher score can be semi-consistently attained if the player really masters the building synergies table, but the reward does not feel like it justifies the effort. Looking at the various components that went into this jam game, though, I can imagine you making a streamlined version of a Theme Park or Sim City inspired game if you wanted to (similarly to how Plants vs. Zombies is a streamlined tower defense game).
As I get the feeling that you are far better at prototyping than I am and also have all your design marbles together, there's really not much to say aside from describing the game experience I had. So I'll just leave it at that.
In all, I didnt' really have "fun" but do appreciate the work and intention that went into it. If nothing else, it does succeed in being experimental, and the polish feels very complete. Very nice work!
