So there's a few things that really need to be addressed/fixed before you put the final version out:
The map doesn't have any built-in regen from what I can tell? You literally have to use full regen, which makes certain jumps easier because you have unlimited ammo. It's not a big deal if that's what you want, to have unlimited regen, I just think it should be built in to the map if that's the case.
Jump 5: If you land on the water in front of start of this jump you get sent back to jump 4:

Jump 6: Is this supposed to be backwards?

Jump 9: The invisible barrier that makes it so you can't smack the sides of these shootable walls is good

Jump 11: There's really no indication of how you're supposed to do this jump, adding "x2" or just a simple marker on the end wall is a good enough way to tell people what they're supposed to do. I think the biggest problem I have with this jump personally, is that it's more difficult to get then the next 2 jumps, so it kind of feels out of place. I think lowering the height you have to get by a bit is a good way to make it so you still have to hit the wallsync, but doesn't require it to be as good.
Overall I like this map, the jumps are pretty well spaced, and personally having it be entirely connected together makes it more fun to run. And I like the mixture of dev textures + actual detailing throughout the map. I think if you address the things I've pointed out, this would be a really good map.
