Sorry that it wasn't clear - you've gotta use the dash ability on that level. You can activate dash by pressing LShift while holding a direction.
Hi, I was able to use the dash to get past the first couple platforms. That was plenty clear, well done! But on the far left there's a platform above you which I can't reach...jumping up gets me level but not on top of that one.
You can dash upwards by holding down W as you dash :)
Wow, I'm dumb :p
Awesome game!
