An important point, simply told.
Letting the game start in a fairly calm state, and then throwing in the natural disasters is a neat plot-twist. Actually shrinking the world and loosing buildings makes the struggle a personal one since they are 'your' buildings and forests. Disasters also adds a bit of dynamic since stats are effected in unpredictable ways by disasters.
The UI/UX is clear and easy to understand. Bonus point for the built in volume controls. Music is elegant and recognizable, without getting repetitive (I'm still listening to it as i type). Graphics are feel polished without being cluttered.
This is probably my favourite in this jam so far (although I've only rated 10~ entries or so).
