What is wrong with world? Now, this world is broken down into pieces. We must put them together to make a world piece before nuclear bombs are dropped.
but why is the next piece a bomb? Doesn't that ruin the whole set up? As in "use a bomb to make peace". Your world map is made out of tetris parts, and that in itself is a good idea and a nice play on the concept. But placing that bomb there turn it around. Why not a peace symbol and stay with the positive flow here?? As your image of the world map is almost complete, and it looks unified and all, the next piece should be your end result: peace.
thanks for clearing that, and I like that you give this thing a lot of thought.
What if you do put the timer above the bomb; as this is the threat? I'm thinking if it is the next piece, the gamer has to use that piece. Instead if it is the timer, a countdown-to-doom thing, then it is still the user who can create peace in time by 'completing the puzzle'.
I like it, but the text takes up too much of the focus, try putting it underneath the game and maybe cutting it down to just a few words like "make peace" or "put the pieces together". The whole thing just seems like a little too much.
