The map itself is ok, but there are some issues.
First, the big one. I can’t find any way of getting past the wind that pushes you into the lava wall. Tried everything, running as fast as possible, running jump, pushing against it and wiggling sideways, strategically placing grenades so as to get an extra push. Nothing was enough to get that small distance that always seems to be lacking. Had to resort to noclip.
Second, the lava portal. Just, why? You literally have to lose a bunch a health, everytime you go through that. And the map forces you to do that, at least twice.
Other annoyances include the first teleporter being a pain to get into, because the frame is so small. Sometimes having to wait for a long time in the room with the two moving, overlapping blocks.
