yeah, I got caught up in adding more pieces to the Level Generator and ran out of time without having added the actual obstacles. The original design idea called for Pipes and Blocks to obstruct the way, with some turrets on the plattforms in the larger rooms. As it is right now, there isn´t really a challange since in most room- and corridor segments, the central path is unobstructed and besides the core, there is nothing to shoot at.
