Could you elaborate on how this plays out a bit more? It seems the whole gameplay is summarised as: “everything can be crushed and destroyed, but almost everything can also duck into and hide themselves for disasters.” How would this make a game?
It makes a lot of sandbox games fun, but your game isn’t really a sandbox game since there is a very strong sense of urgency—a time limit.
Say I have been walking around and collected me some ammunition and food. Then suddenly people are screaming because a tsunami is going to hit. Aren’t my gaming options for surviving limited to picking a place to hide? Like in a house, on a house, in a car, in a tree, &c.? And then I wait there for the tsunami to pass by and I either die or survive…
To me, just picking a location and waiting for whatever my fate might be doesn’t sound like much of a game. Maybe I’m just not getting the idea.
