Unnatural Disaster

This game is great but on level 9 on day one it says destroy any building but if I destroy a building it says I lose and it's getting frustrating

I like the game but level 08 on day 1 might have a problem because I don’t have any disasters and the landslide I think it is keeps destroying over the goal limit and causing me to fail the level every time I restart or start the level

First, could you add bridges, cars, and other forms of transportation? Second, could you add more types of disasters, such as kaiju, sinkholes, etc? Third, could you add the defenses in the campaign into the sandbox mode?
