OMG, I loved the perspective change from the original game! This is how the little shooter has been witnessing the invasion all this time; it's so much scarier this way!
At first, I thought I was supposed to shoot the spheres, and the moving blocks on the ground were there to crash me, like obstacles to avoid :D. But then I figured it out and found the idea brilliant and funny.
Looking up and shooting felt a bit awkward, and I wasn't able to tell whether I could shoot the target or not either.
But other than that, it's a great take and execution!
