I have been building a game a bit like Everything. I.e. you can grow and shrink from basically the size of the universe to an atom. You can pick up things put things down, climb on things, fly about and shoot things. But basically I need some ideas how to make it into a game with a goal or enemies or things like that. One idea i had was that your goal is to collect dna from different alien animals in the universe to make a super organism. But maybe that might be too boring. Any ideas?
