I would have some suggestions for the game (sorry for bad English, I am French)
1, by report has the loss of oxygen, and the cleaning of solar panels, its would be good that we can build a robot or a drone which would repair the base and the other things. He would be expensive in resources and should be powered.
2, a more detailed map, with a legend maybe.
3,longest days and nights
4, entrances of caves which would lead us in caves with mobs maybe, and especially other ores (silver, copper, gold?) and vegetables.
5, storms which would hurt us and would cause damage has the bas.
6, and finally more vehicles, more expensive in resources and can be even on spaceship which would pass by top of rock and maybe go on other planets
thanks to have read my suggestions
