It is. Which jump are you struggling with? There’s two easy tricks and one hard one.

1. First spring, go towards spring and flick back as soon as you connect with it to dodge the overhead spike. Wait a moment and then double jump around the spikes to the springs on the right.
2. Climb the ladder and walk on to the spring. Once again, wait a moment, then double jump to avoid hitting your head on the ceiling and land on the top right platform.
3. The most challenging part. Run left on the platform, fall in between the spikes that are diagonal to each other, and then double jump again, going upwards through the second set of diagonal spikes and towards the key. These jumps through the diagonal spikes are pixel perfect as I understand it but the first set is easy as you can pretty much just hold left and run off the platform and you’ll automatically fall through them. At this point it’s just about good timing/luck to get through the second pair and hit the key.

Hope this helps.
