Thanks for the feedback!
The death is a bit long, but for those hard jumps, utilizing the ‘dive’ feature is key, as it pushes you upward and higher.

Thank you for clearing that up. My bad for not reading the description carefully!
I was now able to play through it! But there is this bug when you do the dive and collide with a ceiling, you get infinite upwards momentum. You can basically skip the middle section, where there is this long bridge above you when you dive against the ceiling.
Anyhow i liked the game much more with the dive key and respawn time didnt seem so long anymore :)
