This is actually good to have kept the partial translation, it proves you worked on it, even if it's not finalized.
Concerning the movements (I'm talking about the walking speed, not the mouse speed), they're fast in both levels. They're faster than what we have in FPS like Unreal Tournament (the 1998 one) or Xonotic. I think that running this fast should be kept right after being shrunk until we enter the second level (to emphasize the escape).
