This is , Different.
I Like the physics and mechanics, graphics are nothing new and I don't care for graphics but I do care for game play , what this game has plenty of, you should be proud of this as this has A LOT of potential
I Like this game, ALOT
The atrocious load time, along with the fairly crappy load screen and start menu, made the game uninteresting at first. But once the game started, it became exponentially impressive over time (not linearly, but exponentially).
This game deserves a 5-star rating (on the bet that the load screen and start menu will be improved later).
However, the music is not a good fit at all. It just doesn't belong in this game. It'll be understandable if there's a certain theme behind it, but it would make the game (and the designers) so much more credible, if the music was mean and suspenseful. Hopefully, that was just a test sound file that accidentally made it in the release build.
There's a lot going on already with plenty of sound effects, so the music might not have to be as busy as it is.
Overall, this is a pretty damn mean game. Outstanding controls. Great job.
