"Instable Polar Dimension"
Shouldn't it be UNstable Polar Dimension?
"That doesn't sound too well..."
Um... it's "That doesn't sound too GOOD..." (not being grammarnazi, just OCD about this stuff).
Also, WHY ISN'T THIS A FEATURED LEVEL?!
Dimension Stability - 40-90%
That just doesn't sound right to me. Maybe it should be Dimensional Stability (I don't know why it says dimentional is wrong...) , Dimention's Stability, or Dimention Instability - it just doesn't sound right to me (no grammarnazi here, just an opinion).
