I think the gameplay is very smooth but the annoying jump button, Ctrl, is very hard to press when I need it, you know pinky. I'd rather use the Space key to jump. Otherwise. 3/5
I got 25 diamonds on the second try. Just max out your thing, Well I had it so you might have to, and go to the deepest part. Stay on the safety zone, between the change of ground, and go right or left, click to collect hard to get diamonds, and then BAM. I got 27 of them.
One thing I don't like is that when you hold Obama the camera gets fixed on the background. If it was fixed on Obama ALWAYS then I would rate it 5/5. Awesome song. So 3/5. Work on it!
