Oh no! I am sorry to hear that! I played through it a few times, but didn't encounter that bug. I'll take a look at the build. I did reduce the jump height when you're standing still. Did you try walking towards the pillar and jumping at the same time? Because the jump height is doubled if you jump while walking.
Either way I am sorry. I'll have to fix that in an updated release build. Thank you for your feedback Arvid!
