You can now create new levels and share them over Steam Workshop! Read the Level Editing Guide and make metal moan!
Other stuff:
- Free Cam added! See the crashes from any angle with WASD+LMB! (And Q, E, ctrl and shift)
- Hide the on-screen HUD with ctrl-h for perfect video captures!
There are lots more fixes here and there, but you can read about them on the forums. Join the discussion there!
