How do you skip the jumps scenes? Like in avalanche I see everyone skipping that intro and i can't figure out how to do so.

Followed the instructions from that with the game completed and it still does not let me :/

Make sure you complete the game after the changes in config with all checkpoints(without skip in last level)

I have, and still nothing

I have the steam version not sure if that changes anything
