Stay away from this game.
It's too random, the shots are too weak, and when you do manage to shoot something down, it comes at you and can hurt you! Why shoot, then? It only makes life harder for you. The only real reason is when there's a huge wall of 0s and 1s in which it would be otherwise impossible to pass unharmed. Also, unlimited mode should have a timer. Sucks guessing when it's good enough.
102 seconds, got the achievement, never wanna play this game again.
