Game demo#999

There could be a demo on steam, so that people could play a little bit with the game before deciding whether they give it a shot or not.
This could be done by throwing them into a new game, but drillships can’t go underground, blast shelters can’t be opened and the submarine isn’t a safe place so you’d have to die at the eruption, leaving you about 10~15 mins to mess around and get a feel for the game.
Of course, this doesn’t give a full impression of what the game is, which is why there could also be a second mode, where you have access to a full ship, and all items and modules so you can mess around and see how the build system works and what you can do with it. This also has to be limited in time, of course.
