I don't know all about Ares's builds, but I don't think it's one of theirs. Their's always have more ramp bricks, but, this may just be unfinished on the exterior.
It's interesting though.
How did you even get that effect at the bottom of the screen?
It might be a glitch from changing to FullScreen or changing the resolution.
Some of my games do that momentarily when I change the window size.
