Patrons Poll: Why is there a time limit? (Patreon)

There will be a time limit in "Gts Management" for gameplay reasons. The question is why would there be a time limit, story wise?

1-The giantesses will breathe the entire air of the planet, the tinies will die.

2-The portal link from the giantesses homeworld will be shut down.

3-Angel the giantess will become unstable and destroy the portal and the tinies.

4-The tinies will become crazy and destroy the portal to keep the giantesses.

5-The powerful giantesses foot odor will saturate the air and kill the tinies.
