Hello 👋 dev here ^^
The third before last level might be a bit too hard from what I understand (the one with the bulls/charging enemies). Feel free to use the level select to skip ahead to the "Where is She ?" level which is the one right after, you wont miss any part of the story by doing so.
You can access the level select menu via the pause menu (Esc, P or "start" on a gamepad)
