So I added/extended the catwalks, shown as the red part in the picture. With that, if you start from the health pack room, you can go directly to the catwalk or wall-run to pass the lift to it, then from there a dodge can land you on the other catwalk. If you come from the belt side, a dodge is not enough, you need a wall dodge to reach the lift catwalk, that extra effort is good for the belt side in terms of balance. The lift can be approached from the right, and it opens an opportunity to go lift jumping back to the 3rd level next to the belt.

I went through a series of comparisons of the ground areas on the different sides of the map, and found the jump pad tunnel side, which is in the above picture, needs a bit more ground space, to make you a bit more secured to move around here and that makes the feeling of the space a bit more satisfying. Previously the opposite side feels a bit more comfortable as it has a bit more space, but now it feels balanced.

The top level catwalk, highlighted in the above picture, is wider, by 10 cm. Not much, but enough to make the navigation comfortable and the navmesh good everywhere on it.

The jump pad landing zones are all tweaked, especially the two on the jump pad tunnel side (the two on the right of the picture), they are bigger compared to the previous version. The jump pads are also tweaked accordingly to allow you nice air control to go a bit sideways but you can ALWAYS land (unless of course you press back button to reduce forward momentum)
