I released an updated version and the story is more clear and I think I fixed the sliding (unsure if I it did anything) .

I was able to finish it this time. The most difficult part is still "the floor is ice". The character takes a second to come to halt after you press forward and glitches off corners. In Unity I'd say it is a capsule collider without friction. I don't know how it is in Godot. :)
Still... this can all be part of the challenge and building and jumping is fun. Good job with that idea! :)
