There is no kill volume on the first map, my bad! If you are struggling with the movement I highly encourage you to try it out in the shop level, and if the first wallrun is too difficult you could outright skip it, here are 2 alt ways to beat level1, but none of these are actually the fastest.
And if you fall on those first jumps and dont know how to get up - you can can jump on a wall sideways and then jump up again to get out of the space between the platforms. Oh and don't quit if you lost to the timer, all the upgrades stay with you! You can "break" the game by stacking lots of those.
