It's a very fun and creative idea!
I think you did an amazing job given the short time limit. I had the exact same issue of having to limit the scope even though I had more ideas.
The game has a lot of potential. I think it would be fun if everything had a proper interaction. I'm sure if you had 10 people play the game, all of them would come up with different creative ideas you hadn't thought of yet. Implementing all the ideas is another story. I'm sure the current game was already very challenging to implement.
Once again, great job!
