You can destroy all of the objects, but you must be careful - some of them have hidden traps that can kill you. If you trigger an invisible mine, for example, you will die and all of the items in your inventory will be lost. Your options are limited, and you must choose wisely.

The weapons and tools you use have different effects. You can shoot and blow up everything you see, but you must be careful to avoid using the wrong tool in the wrong situation.
