Story Hints,

The installed .exe has been renamed and Steam didn't find it in my drive D :
Just copied and renamed the folder "Ignatius - Reunited_Data" to "Ignatius_Data", and the exe "Ignatius - Reunited.exe" to "Ignatius.exe", and Steam worked ok (otherwise no played time is registered).

After killing the ball with electricity alternating 2 switches, you arrive at a level with dipping air slabs.
You then get to a place with electric transformers, put a missing part in a group of 5 transformers.
Beyond there is a metal slab barring progress.
Go back moving a crate, to 5 buttons, push them so :
yes no yes no no no
This lowers the metal slab (cutscene), go on.

Farther in the game, you find a panel :
Panel default, vs panel arranged for metal slab going down (cutscene).
yes yes yes yes yes no
yes yes yes yes no no
yes yes yes yes yes no
