I agree with you. The scope was too big, and even designing those puzzles was not hard. For sure it requires better visualization of data and the relation between them. I even considered not submitting it, but I would regret the effort put into the game.
Everything needs more balancing end a better level editor (I only had a simple inspector to select buildings). It would require more combination of storage.
I have planned to add the winning condition threshold but run out of time. Plans for the tutorial were also bigger ;)
