I've only seen 2 games with this concept (includes this one), and it's great how you managed to make this in a week. There's a variety of different buildings, but I don't know what each one really does for me, a proper tutorial would help (I've definitely learned that from my game lol). The game looks amazing and the music fits in very well, but I can tell it's somewhat loud for anyone using headphones. Overall, nice work! Enjoyed it.
Edit: One more thing I think would help, being able to move the camera would help a lot so that it's not stuck in one position, but that's just a quality of life thing, so it didn't affect my experience too much.
Edit 2: Okay, I think I figured out how to actually play, it took some time, but I think I have the strategy down. Definitely recommend if you like games with long term progression (probably 15 - 25 min per game).
