Wow, thanks for the in-depth review - I appreciate it! I agree that the objectives could be more engaging and could somehow be reworked to fit the game jam's theme. I think in the game's current state there's not too much going on and it lacks feedback or something for the player to work towards since there isn't any puzzling or challenge required to complete the objectives.
After giving it a second thought, I think if you can *somehow* keep track of objectives tasking the player to make new small areas, it would force you to not rely on a single perfectly spaced colossal area of each tile and at that point you literally have to build (to scale) for the later potential objectives ahead of time. Might add a lot to the puzzle aspect of it.
