Thanks for your feedback anyway.
Yeah, I've figured out that some levels are very difficult and that I have named the levels at the end all the same. I will fix that.
For this level *Spoiler Solution*:
Jump right over the spike. Before the fake platform at the end jump onto the hidden playform (the upper one). Jump on the highest playform. Avoid the spike. Just walk and fall onto a platform. Go right (there is the goal).
I hope this helps
Thanks for playing...
