Hellraiser
Arcane
There's something about the UI that annoys me but I can't tell exactly what. I guess it's a bit "unclear" ? It doesn't immediately communicate what you chose or what each thing does?
My only gripe with the UI is the blur straight out of win7 Aero. Classical coloured transparency maybe with some blending effect would look better. Also there is a lack of borders on the UI elements, which I guess can work, but for me it doesn't look good. But those are minor things.
Otherwise the game looks good, both bac9 and C7 did good stuff for KSP .
