Ultrakill Clash mode [Prelude]

I did a run through once before this, but forgot to press record...
The funny part is that 0-4's opening, despite just kinda clearing it with relative ease here, was easily the hardest part the first time through. the last part of 0-2 didn't even give me that much trouble before. Oh, I will have one bit of advice: the reason you can't cheese by going into the crusher at the end of 0-2 is that you actually can't make the jump back out.
it might be possible to just slidejump super optimally or something in 0-5 but since you can't walljump I'm not quite sure what to do besides just like. Doing the level.
