We were indeed going to have better options for water supply after progressing further with the game, but like you have correctly guessed, we did run out of time. Also we were meant to have selling/destroying buildings added which would have felt better than the current state at which the wells run out of water and are but only a waste of space. It would have also made more sense if we were to go with limited resources for everything, including trees and rocks rather than respawning, which was a plan, but would not work for the game jam.
