When using angle turn (a.k.a corner/90 degrees/half pi radians/stairway to heaven) there are situations when the curve is perpendicular to another curve/wall and just before you die, you smash that left/right key.
The bug is that you die anyway. At first i thought my reaction is too slow, but I’m preety sure by now this is a bug. Best example is doing 180° turns and getting closer to the wall. Usually you can touch the wall without dying but not when cornering.
I hope I was clear, but just to be safe I’ll include this replay: https://curvefever.pro/56/replay/Jrhh1ZgOv
First 2 rounds are good enough examples.
You can prove me wrong by touching the wall with corner
