it already comes out

soon ,i will publich remake of this collection

There are a few key issues, the barrier over the second portal spot blocking the bridge unless its create at a certain angle, the fact that you can jump down to big cube at the bottom of the first area and get stuck (usually you'll die if you go someplace you're not supposed to), and how on the second bridge you literally just walk through steel beams. besides that this map is really fun to play and I like how broken it is, haven't seen a map give off destroyed building feel. I think this map shows your improvement really well and you should keep at it.

Nice. A bit crude design in some places.
