So... since I started I have learned a few things:
I'll be rewriting Zelia to teach myself godot 4.1.1
I'll be sharing this experience on github, possibly you'd care to join?:
https://github.com/Teaching-myself-Godot/rewriting-zelia-tutorial#learning-godot...

Fixes in v0.1.1:
- adds tutorial for gamepad
- fixes keyboard-jump soft lock when entering 'worm nest of operations XD'-map from start-map

Fixes in v0.1.0:
- tutorial for keyboard and mouse now correctly states to use up-arrow or 'w' to open doors (in stead of spacebar)
