Awesome game! Nice sounds, you can really feel the velocity.
I'm still a little dizzy... maybe because it's 3 AM.
I bet someday this game will be famous and "banned-in-many-countries" because of provoking side effects on children XD... cool.
At first it felt like if you play it too much you will like shock a little when you crash at high velocity, but when it turns out that it isn't like that it leaves you like wishing to be able to feel the crashes at least a little. I could be feeling that because of my limited screen... but it still feels like if the sensation could be felt anyways, somehow. Well, obviously if you could use the VR-vision-goggles with this game you should feel those crashes a little... but it still feels like if the sensation of crashing doesn't depend of the screen size.
Nice use of the Unity Engine! It's the first game I see in Newgrounds that uses something like it... and that has fullscreen (awesome!). It is also like the third 3D game I've seen around here (the first one was Doom triple pack xd).
And yeah, you should fix the 4-moving-squares-part, maybe just making them a little transparent. It's just that sometimes it's impossible to avoid that fast-moving-square from behind the very-still-square that you just got past. The thing it that most times you can't see the moving ones behind the still ones.
