What? Did I go back in time? v1_r3 is not nearly as good as spacecastles2. Where's the teleporter? That thing was sweet.
The wall in the middle is too easy to jump. Perhaps make it wider and add a moving platform.
Box maps are so last year, throw a kink in there. Streich the length from the castle to the wall too. I can laser jump from the castle to the wall, I don't think I should be able to.
