Oh, so fast fixing means you want this map on the server so bad ;D Sorry for much text.
It's not your first map, don't lie D: It's too good for that!
It's 100% Brutal, and this oldschool style that people want.
You know, I hate edgejumps and 50% of your map is only that. Only acceptable edgejump for me is on 3 tiles platform where I can hammer my mate on edge, 1 tile where I can push him, or if we have laser - then size doesn't matter
I rly like first part. 3rd part where you have to go up and only edgejumps is TERRIBLE and I can't imagine how you should do it. It's like Brutal 5* because you can't help people down there who fell down. Then nice hammerhit, very cool hammerfly and those 2 fly parts <3. Some standard parts, dummy drag, nice laser parts.
Ye, it's next map like Genericore or Hardcores so server will be full because people will play it in huge groups. For me this type of maps are only rescue - trainings.
I have to say, it's even pretty mapped. Animations exactly 360°, editor not messy - not 20 layers, separately for unfreeze, deep and eveything else. I'm impressed, it's a solid map (learned it from Ama

), not random parts and ideas.
So, here my suggestions and 2 bugs, but do what you want, fix it like you want:
Please make this things spinning slower, it can be very disturbing when you have so fast moving thing in your screen + all tees + you are in air and everything together (same with big hammer - it's even worse). I would also remove a few of them, sometimes you have 4 wheels in your screen.
You reduced only Game layers size, please make it with others (freeze, hook etc) layers too.
